Aims

To develop a basic understanding of genetic principles and their application in biology.
To give an introduction to the concepts and principles of inheritance of genetic characters, their recombination and linkages.
To give a basic understanding of the genetic code and the replication of DNA.
To outline how genes are expressed into proteins, via transcription and translation.
To review the methods used to study the genetic material and how these methods are used in different applications.
To review the evidence for evolution from the fossil record, earth history, and comparisons of living organisms in terms of structure, function and genetic constitution.
To outline mechanisms for evolution, especially in terms of artificial and natural selection and genetic drift.
To explore the observational and experimental evidence for the role of these mechanisms in causing evolution.

Teaching Methods

Please note that module leaders are reviewing the module teaching and assessment methods for Semester 2 modules, in light of the Covid-19 restrictions. There may also be a few further changes to Semester 1 modules. Final information will be available by the end of August 2020 in for Semester 1 modules and the end of October 2020 for Semester 2 modules.

Teaching Rationale And Relationship

The main body of factual information is delivered by means of lectures.
Some of the fundamental concepts are reinforced by the group teaching activities and practical exercises, plus independent exercise work and worksheet exercises.
The practicals introduce the necessary skills we are seeking to impart

Assessment Rationale And Relationship

Lectures and practical materials together with the directed reading provide questions for formal assessment based on the knowledge acquired during these activities. The assessment will focus on testing depth and breadth of factual knowledge and general understanding of the concepts and implications in each subject area. The practical reports and in class tests are designed to assess the ability to understand and perform practical activities, record findings and interpret experimental results.
