Introductory description

The module aims to achieve a more in depth understanding of the basics of molecular biology. Students will understand the organisation and complexity of the sequence constitution of chromosomes in both Pro- and Eukaryotes. They will be able to understand how genes are controlled by building on the basics learnt in LF130 Molecular Cell Biology on the nature of transcriptional control. They will be able to place this understanding into the context of chromatin remodelling, and will be introduced into the molecular biology of epigenetics. Students will gain an understanding of the mechanism of other layers of post-transcriptional/translational/post-translational control. They will be introduced into modern molecular methods and how they are used to study modern biological problems.

Understanding the biology of eukaryotic organisms requires knowledge of their organisation and operation at the cellular level. An appreciation of the means by which cells perform their many functions is a prerequisite for detailed study of the underlying biochemistry. This module does not cover the entire range of subjects that could be included under the heading of Cell Biology but concentrates on key areas to illustrate principles and to allow students access to the wider range of information available in modern texts.

Learning outcomes

By the end of the module, students should be able to:

• Students will understand the organisation and complexity of the sequence constitution of chromosomes in both Prokaryotes and Eukaryotes.
• They will be able to understand how genes are controlled by building on the basics learnt in LF130 on the nature of transcriptional control
• They will be able to place this understanding into the context of chromatin remodelling, and will be introduced into the molecular biology of epigenetics
• Students will gain an understanding of the mechanism of other layers of post-transcriptional/translational/post-translational control
• They will be introduced into modern molecular methods and how they are used to study modern biological problems.
• Students will gain a detailed understanding of the biology that underlies the fundamental cellular processes of such as the control of cellular activities, the major forms of the cytoskeleton and the process of cell death.
• The principles that underpin the current understanding of these processes and their impact on development and disease form the basis of this module.
