An Introduction to Bioinformatics

The purpose of this chapter is to illustrate how to obtain information on DNA and protein sequences from databases. This is most conveniently achieved using a Web browser (Netscape or Internet Explorer). This chapter is loosely based on a course given by the author at the University of Hertfordshire from a set of Web pages that facilitate Internet navigation by using hyperlinks and allow sequences to be copied from the Web page and pasted into the relevant search engine. (The online version of this information can be found at http://www.herts.ac.uk/natsci/Bio/informatics.htm .)
