Topic 8

THE CONTROL OF GENE EXPRESSION

WORKSHEETS

PRESENTATIONS

Studying nucleic acids in Topic 1 and 4 clearly wasn't enough because in Topic 8 DNA is once again the focus. Interesting and exciting in equal measure, this topic leads you through some cutting-edge science and the potential applications. These include the uses of stem cells and genetically modified organisms, potential treatments for cancer, how the process of DNA fingerprinting works and the use of DNA fragments in gene probes. You'll also learn how a cell knows which genes to use at what times and the uses of genome projects.


Use the worksheets alongside your textbook and revision guide. The presentations are more for teacher use but students may also find something useful in them.
