Genetics is the study of biological information; how it is coded, copied, expressed, transmitted between individuals and changed to give variation. As such, it is central to contemporary biological thinking and research, both as a topic in its own right and as a tool in the investigation of other areas of biology. This module will demonstrate how the organisation and structure of genes and genomes may be investigated in prokaryotes and higher organisms. The basis by which genetic variation arises and is transmitted from generation to generation will be discussed. The module will also introduce the phenomenon of epigenetic inheritance. The molecular basis of prokaryotic and eukaryotic gene regulation will be described together with an introduction into the methods used to analyse gene expression. Students will gain experience of a range of genetical techniques. In addition, as genetics is an analytical subject, particular emphasis is given to developing critical thinking and quantitative skills through problem solving.
