Module summary

Genetics is all you wanted to know about sex but never dared to ask! - What makes us human? - What makes us individual? - How different are we from each other? - How similar are we to other species? - Only Genetics provides the answers. We - and all other living organisms - are the product of the genetic information we contain. We pass that information on from one generation to the next in ever-changing combinations.This module describes the nature of the genetic material - DNA - and how it is transmitted from parents to offspring. The form and function of living organisms is determined by the genetic information they contain, and how that genetic information is interpreted. The diversity of living organisms derives from how their genetic content has changed, over hundreds of millions of years. We examine the way in which the genetic material encodes biological information, how that information is replicated and how it is expressed in a regulated manner within organisms. We also examine the technologies that allow us to isolate individual genes, sequence them, manipulate them, and analyse whole genomes. If you have a good understanding of Biology, are curious about the secrets of life and are ready for an intellectual challenge, then this module is for you.


Learning outcomes
On completion of the module students will be able to:
- have a basic knowledge of inheritance in prokaryotes, eukaryotes and their viruses at the molecular, cellular and organismal
- understand the experimental basis of key genetic conclusions.


The module provides an introduction to genetics with particular emphasis on cellular and molecular mechanisms, and covers the principle features of the transmission, replication, modification and expression of genetic information in prokaryotes and their viruses, and in eukaryotes.

Subjects covered include:
- the replication of DNA
- the modification of DNA by recombination, by mutation, by transposition and in the laboratory
- patterns of inheritance in bacteria
- in viruses
- in eukaryotic microbes and in higher organisms (including humans), gene/environment interactions
- the regulation of gene expression in viruses, bacteria and eukaryotes
- genetic switches
- the genetic regulation of development.

The module introduces the basic methods used in genetic engineering and molecular genetic analysis.
