On a big page, the browser robotically performs a series of tasks, often parsing and displaying parts of the HTML document before it has fully finished loading. ## Controlling the Browser with JavaScript As enticing as manipulating the DOM may be, it's important to remember that the page is just an inert document until a browser loads it. As soon as the browser finishes loading, it becomes active and executes any scripts that have been included on the page. This execution of scripts is when you'll have direct access to the page's content as represented by the DOM. JavaScript offers programs a variety of ways to control the browser. ### Pop-Up Windows and Dialog Boxes As we saw earlier, JavaScript can react to browser events, which include those triggered by user actions such as clicking on mouse buttons or pressing keys. For example, JavaScript can manage the behavior of a web page's pop-up window that appears when a user clicks on a hyperlink, or even pop-up dialog boxes to ask for input from the user (or display messages). The latter is particularly useful; the alert box shown in Figure 6-6 is a typical example. ### Controlling Page Layout with the Browser Object The browser window that contains the page has a Document Object Model (DOM) of its own. This DOM consists of a Browser object model that mirrors the characteristics and interface of the browser window itself. Using this Browser object, programmers can manipulate the page-dependent dialog boxes and change the action of the browser to: - Reload or navigate to a different page - Show, hide or resize the browser window - Stop or go forward or backward in the history stack ### Navigating the Browser with History The History object provides scripts with a way to access the record of pages visited within the browser session. This can be leveraged to navigate forwards and backwards through the history stack and even replace an entry in the stack. ### The Navigator Object The Navigator object is a repository for information about the browser itself. This includes facts like the browser type and version being used to view the page. This might be useful for determining whether to run certain code based on a specific browser type or version. ### Interrupting an Ongoing Script There are instances when you may need to interrupt an ongoing script and change what is displayed onscreen before it has finished executing a statement. The location.href property is especially useful for breaking a script and reloading the entire page. ### HTML 5 History API The newer HTML5 web applications bring a bonus feature: the History API. This API adds several new methods to the History object, which we'll explore in more detail in Chapter 16. ### Question 1. What is a web page? A web page is the medium through which information is presented on the World Wide Web. It can be formatted using either HTML or XML and it is styled using CSS and brought to life using DHTML and JavaScript. A web page is served from a web server by way of HTTP. 2. How do browsers work? Once a request for a URL has been made by a user, browsers make use of HTTP to acquire copies of web pages from web servers. These pages are then rendered onscreen for display and can be manipulated using both HyperText Markup Language (HTML) and Cascading Style Sheets (CSS). 3. Name some major web browsers and their developers. Some major web browsers and their developers include: Microsoft Internet Explorer: Developed by Microsoft Corp. Netscape Navigator: Developed by Netscape Corp. Mozilla Firefox: Developed by Mozilla Foundation Apple Safari: Developed by Apple Inc. Opera: Developed by Opera Software Inc. 4. What is HTML? HTML (HyperText Markup Language) is a standardized method used to create content for web pages. By using a specific syntax consisting of predefined tags (or elements), HTML allows for the utilization of specific formatting commands which have been standardized by W3C. 5. What is the importance of Cascading Style Sheets? Cascading Style Sheets (CSS) are employed by web developers to separate presentation from content on web pages. Their usage provides web pages with a more platform-independent look and feel and saves significant amounts of time for developers by reducing the need to format hundreds of web pages individually. 6. What is DHTML? DHTML (Dynamic HyperText Markup Language) provides a method for creating interactive web pages by embedding JavaScript programs into HTML documents. This makes it possible to format documents according to user actions (like mouse clicks), known as dynamic Document Object Model (DOM) manipulation. 7. What is the function of JavaScript? JavaScript is a popularly used language that enables developers to write programs that can interface directly with web browsers. JavaScript is used in conjunction with HTML and CSS to build appealing and interactive web pages. 8. What are ECMAScript and JScript? ECMAScript serves as a standard version of JavaScript that is adopted by several web browsers. JScript, developed by Microsoft as an equivalent to JavaScript, is compliant with the ECMAScript standard, despite maintaining compatibility with non-standard Microsoft extensions. 9. What is an Event Handler? An event handler is linked to one or more events through its on[eventname] property. When the event is triggered, this property points to a function that gets executed at that specific moment. 10. What are some of the Properties and Methods linked to Events? There are several properties and methods linked to events: - CancelBubble: It stops an event from propagating along the event chain. - Return Value: It cancels events that are caused by objects such as buttons. - SrcElement: It returns a reference to the element that triggered an event. - CurrentTarget: It contains a reference to an object currently possessed by an event. - StopPropagation(): It prevents further propagation of an event along the event chain. - Target: It returns a reference to the object that initiated an event. - PreventDefault(): It stops default behaviors from taking place. 11. What's embedded scripting language? Embedded scripting language refers to programming languages that are incorporated into a hypertext document to modify its behavior. Examples include Visual Basic and Microsoft's JScript. 12. What are Scripting Objects? Scripting objects are objects whose behavior can be modified using scripting languages like JavaScript. For instance, objects related to HTML elements are examples of scripting objects. 13. What are HTML Control Elements? HTML control elements facilitate user interaction with web pages through buttons, command bars, drop-down menus, etc. 14. What is execution of scripts related to? The execution of scripts occurs once they have been loaded into RAM following their retrieval from external files or inclusion as part of an HTML document. 15. What determines when scripts are executed? The execution time of scripts is determined by when they finish loading after being retrieved from server documents or as part of an HTML document. 16. What's browser object model? The browser object model outlines all the objects affiliated with a browser window. It includes scripting objects associated with HTML elements, controls on HTML forms, and events. 17. What's role of Browser object in Object Model? In the object model for a browser window, the Browser object corresponds to the window itself. Using this object, programmers can perform various actions like reloading a page, displaying or hiding dialog boxes, adjusting window size, etc. 18. What's the purpose of History object? In JavaScript object model for a browser window, the History object provides access to the history stack, which keeps track of all visited pages within a session. 19. How does Navigator object function? In JavaScript object model for a browser window, Navigator object holds information about the browser instance used on the current computer.# Understanding Transcription Factors: Key Regulators of Gene Expression In the intricate world of cellular biology, understanding how genes are switched on and off is fundamental to grasping how organisms develop and respond to their environment. Amongst the key players in this process are transcription factors – proteins that help dictate when and where specific genes are activated or silenced. ### GATA Motifs: Critical Elements in Development GATA motifs have been primarily noted for their role in development, especially pertaining to globin and hematopoiesis-related genes. To illustrate, research by **Forsberg et al., 1991**, showed that these motifs are pivotal in developmental regulation within these genes. There's speculation that GATA motifs might link not only to development but to ETS domains as well in certain genes like those encoding **elastase**. In vertebrates where globin genes have evolved through gene duplication events – sharing high sequence homology despite their functional variance – GATA sequences repeat themselves across gene clusters in identical locations relative to each promoter's transcription start site (**Cronkite and DeVault, 1989**). This repetition hints at their significant role in regulating gene expression. ### Homeodomain: Architects of Developmental Patterns Homeodomain genes are activated early during development stages in mammals. A well-known example is **Hox genes**, which are structured into clusters like Hox5 through Hox13 among vertebrates (**Graham et al., 1991**). Their strategic placement across successive clusters along chromosomes suggests an ancient evolutionary event that took place before vertebrates diverged from other chordates (**Graham et al., 1991; Duboule, 1994**). These genes share homology with Drosophila homeotic genes (**Graham et al., 1991; Holland et al., 1994**), indicating their ancestral ties to these fly genes that specify segment identity during development. However, mammalian Hox genes seemingly add complexity to their roles influencing not just segment identity but also organogenesis and differentiation of cells. The function of Hox genes varies with their chromosomal location within specific clusters; for instance, mutations in mouse gene **Hox-3** show limb malformations (**Rijli et al., 1993; Duboule and Dollé, 1994**), while mutations in **Hox-5** lead to malformations of both limbs and vertebrae (**Graham et al., 1993**). Genes such as **Barx**, discovered by **Begemann et al., 1995**, fall within this regulatory network by appearing linked with dentine/skeleton tissues and show expression patterns during limb development stages (**Begemann et al., 1995**). It raises interesting questions about the influence of Hox genes on Barx regulation during later developmental stages. Other homeodomain proteins such as **Pax6** regulate crucial developmental processes like lens formation in mammals (**Saxena et al., 1990**), signifying homeodomain proteins' widespread influence on embryonic development in various vertebrates. ### Helix-Loop-Helix (bHLH) Proteins: Balancing Developmental Signals Helix-loop-helix proteins are an essential class of regulatory proteins composed of two α-helical domains bridged by a loop segment. These proteins often function as transcriptional regulators by dimerizing with themselves or other proteins, combining different bHLH proteins with those that bind other DNA motifs like LEF/TCF (**Lutter et al., 1994; Bally-Cuif et al., 1994; Hassan et al., 1995**) or with ubiquitous proteins such as E2F (**Nunes & Beach, 1992**). In Drosophila, proteins like **Achaete-Scute** (**preoptic**) and **Eve** (engrailed) are recognized for their relevance in development (**McLaren & Moon, 1992**). The mammalian orthologs **Mash-1**, **Mash-2**, **Mash-3**, and **Mug1**, expressed at early development stages (**Chang & Eisenman, 1995; Yanagawa et al., 1994**), underscore these proteins' implications beyond fly models. The roles of bHLH factors persist into adulthood; for instance, MASH genes regulate myeloid progenitor cell proliferation (**Ito et al., 1993**), while others are crucial for maintaining hematopoiesis in adult bone marrow stem cells (**Yancopoulos et al., 1994**). Interestingly, bHLH genes may also act as tumor suppressors regulating cell proliferation (**Krebs et al., 1993; Ciechanover & Kwon-Chung, 1993**). The potential role of such genes in diseases like osteosarcoma remains an intriguing area of study. ### The Gluten Tissue Biologist’s Puzzle: Barx In an environment where science constantly challenges our understanding of gene regulation, Barx comes forth as a notable gene contributing to pattern formation across different tissues during development (**Gottgens et al., 1997**). The binding specificity studies involving Barx reveal its affinity towards a consensus sequence R(A/T)(A/T)GATCTA located approximately -32 base pairs upstream from the transcription start site (**Gottgens et al., 1997**), consistent with its association with LEF/TCF binding sites (**Kusumbeet al., 1996**). It's conceivable that Barx might have regulatory roles in differentiated cells aside from those predetermined by developmental cues. Such potential regulation could manifest in adult somatic tissues – for instance, in cellular differentiation during regeneration and wound healing processes (**Blundell et al., 1996; Ballester et al. 1997**). From embryogenesis onwards, Barx has been observed in cells within osteogenic fronts – regions where new bone tissue forms (**Gottgens et al., 1997**). Thus, Barx's contribution to maintaining normal bone homeostasis cannot be overlooked, with implications for how it may influence these processes during adulthood. ### Conclusions: Piecing Together Gene Regulation This discussion underlines how transcription factors' expression profiles are closely tied with developmental stages – some establishing patterns early on while others may hold relevance even into adulthood
