Pre-requisite qualificationsThis module will not be suitable for students who have no background in molecular biology or no interest in design and interpretation of experiments.
This module is not approved as a discovery module
Module summaryThis module will give a step-by-step introduction into epigenetics, a subject that covers aspects from various disciplines, including biochemistry, molecular biology, genetics, development, medicine and environmental science.As earlier lectures provide the foundation for the understanding of later lectures, continuous presence and active participation will be essential. The module focuses on how experimental data are obtained and interpreted, which should make the module especially valuable to students who are interested in experimental science.
ObjectivesThis is an advanced topic module that covers a relatively new research area, which has wide implications for our understanding of gene regulation, development and genome structure in different eukaryotic systems. The module will provide you with a good understanding of epigenetic phenomena and mechanisms that have been discovered in animals and plants.
A particular feature of this module is its strong focus on experimental design and on the interpretation of experimental data, which should be of specific value for students who are interested in a postgraduate career in experimental science. The intensive study of original research articles will enable you to interpret experimental data and to design experiments to address specific questions. As earlier lectures provide the foundation for the understanding of later lectures, continuous presence and active participation will be essential. The module focuses on how experimental data are obtained and interpreted, which should make the module especially valuable to students who are interested in experimental science.
The module aims to enhance your knowledge and to stimulate original thinking. In addition to a sound knowledge of facts, which forms the basis of a good understanding of the subject, this module will enable you to use experiments described in the literature to design your own research work programme.
On completion of this module, you should be able to:
- give an account of the history of epigenetics phenomena
- describe the different epigenetic pathways and their interactions
- understand the significance of epigenetics for gene expression, development, genome organisation and genome stability
- understand the contributions of epigenetic effect to somatic cloning, cancer and aging
- describe links between environmental effects and environmental conditions
- interpret and design experiments that examine epigenetic states and that identify endogenous regulators of epigenetic pathways.
The module will improve the students’ ability to analyse data and develop experimental concepts.

Private study- Students will be provided with pdf documents of original publications relevant to the lectures and the practical.
- During the lectures, the relevant research publications will be pointed out to students who are then expected to study these publications with specific emphasis on experimental design and data interpretation.
Opportunities for Formative Feedback- Lectures will focus on scientific knowledge and on a deeper understanding of how experimental data are obtained and interpreted.
- Students will be expected to contribute to the discussion about experimental design and interpretation, for which they should use the information and understanding obtained in earlier lectures. This will provide opportunities for student to monitor their learning progress.
- The lectures are accompanied by three practical sessions where students will analyse original publication that have generated some of the data presented and discussed in the lectures.
- Students will have access to the publication in advance and some experimental details from the publications will be discussed in lectures prior to the practical.
- The students will be asked to answer specific questions under exam conditions to assess their understanding of the subject.
- Feedback will be provided to enable students to monitor their performance.
