In this section you will find James Watson and Francis Crick's Nature classic paper (1953) that first described the double helical structure of DNA. You might be interested to read it for its importance in opening a new age of molecular biology, but also because it is very often analysed in scientific writing courses as an example of effective writing style.
The Gene Gateway Workbook, that is presented in Lecture 5.2. Web resources, will lead you through the bioinformatics resources freely available on the Internet.
