Module description

Genetics and the control of gene expression is the source of diversity both within the body and between individuals; they fundamentally shapes a wide range of biological processes. 

In this module you will be introduced to the fundamental genetic components of the cell and explore how genetic information is stored in eukaryotic cells. You will consider how this information is replicated, how gene expression is regulated, how hereditary patterns arise and how population genetics and evolution contribute. These genetic processes will be illustrated wherever possible with Neuroscientific examples .

Modern techniques in DNA sequencing and the exploration of gene diversity will be introduced, with examples from humans and other organisms. 

To complement the theory of genetics covered in the lectures, you will also observe laboratory demonstrations and have opportunities to explore experimental results. 

This is a core module for the first year students on the BSc Neuroscience programme.

Module aims - intentions of the module

This module introduces you to core concepts in genetics and complements this theory with appropriate laboratory demonstrations. The module will discuss topics including DNA structure and organisation, DNA replications, gene regulation, genetic engineering, the origins of DNA variation and hereditary patterns. 

The theory of various techniques used to study genetics will be discussed to complement the laboratory demonstrations.

Intended Learning Outcomes (ILOs)

Syllabus plan

Whilst the module’s precise content may vary from year to year, an example of an overall structure is as follows:

We will cover topics including

  • DNA and chromosomes
  • DNA to protein
  • Control of gene expression
  • Genetic technologies
  • Mutagenesis and DNA damage repair
  • Genetic variation
  • Genetics patterns and principles of heredity
  • Linkage and mapping
  • Chromosome variations and sex determination
  • Population genetics
  • Evolution

 

These will be covered through lectures, data analysis and laboratory demonstrations.

 

As part of Project Enhance, we are increasing contact time in this module by approximately 20% for the 2021 Academic Year.

Indicative learning resources - Basic reading

Emery’s Elements of Medical Genetics (15th Edition) Elsevier. – Chapter 1 of this book provides a concise introduction into the history and impact of genetics in medicine.  

Russell PJ (2014) iGenetics: Pearson New International Edition: A Molecular Approach – This book explains key concepts from this course at the right level. 

Alberts B et al. (2015) Molecular Biology of the Cell (7th Edition) – This enormous book goes into great depth - more than is required for this course - but the explanations and diagrams are excellent. Chapter 1, “Cells and Genomes” from page 10 brings together key concepts covered in this course in an accessible way.
