Semesters
Semester 1 Credit Value: 20
ECTS Credits: 10.0

Aims

1. To elaborate the methods for and uses of genes and genome sequencing.

2. To elaborate different microbial systems used to express recombinant proteins.

3. To elaborate the methodologies underlying genetic engineering of plants and animals (both vertebrates and invertebrates) from first principles including construction of transgenes and techniques for introducing them into plant/animal cells.

4. To elaborate the use of RNA interference as a means of gene silencing to understand gene function.

5. To elaborate the use of proteomics and transcriptomics for studying gene expression and identification of functional molecular markers.

6. To elaborate genome mapping strategies through different molecular markers.

7. To promote detailed critical analysis of, and engagement with, the latest developments in the field.

Outline Of Syllabus

An introduction to the applications of basic understanding of cell and molecular biology will be provided to appreciate the principles, methods and systems used as foundations for various agricultural, pharmaceutical, medical and biotechnology industries. Areas range from applications in fundamental tools like DNA sequencing to expressing recombinant proteins for research or commercial applications, to generating improved varieties of crop plants and livestock through genetic engineering. The use of functional genomics for studying gene expression and identification of functional molecular markers as well as marker-assisted breeding will be covered. Technologies for gene silencing such as RNAi will also be addressed.

Teaching Rationale And Relationship

The lectures will provide students with the background information on DNA techniques and the labs will allow them to think in more practical terms how to get information from experiments and computer based data analysis. The labs give them the opportunity to practise the techniques discussed in the lectures and to learn how to interpret the data and report the experiments in an appropriate format, preparing them for their future project. The field trips will allow students to see some of the techniques they are studying in use in an industrial setting.

Assessment Methods

The format of resits will be determined by the Board of Examiners

Assessment Rationale And Relationship

The written exam, practical report and mid-semester test will assess the students’ understanding of the subject. The mid-semester test will also act to check students' progress with, and understanding of, the module content.

Study Abroad students may request to take their exam before the semester 1 exam period, in which case the format of the paper may differ from that shown in the MOF. Study Abroad students should contact the school to discuss this.
