Module Aims

The Comparative Genomics section of this module will introduce students to the field of comparative genomics and its many applications. This module will follow the flow of comparative genomic analyses from biological database through to statistical and mathematical models of analyses of data from sequence databanks and micro.  Arrays with the aim of understanding the patterns and signals present.

The Developmental Biology section of this module aims to introduce the basic concept of how a single fertilised egg gives rise to a multicellular organism. The module will focus on the general principles of development identified in a few key model organisms and how these principles can be applied to other organisms in a bid to understand animal development.



Learning Outcomes

The Students will learn the importance of comparative genomics and its applications to molecular biology and genetics. Student will have a clear understanding of: Theory and history of comparative genomics, major comparative genomic methods including:

  • sequence alignment - both pairwise and multiple
  • probability and statistical analysis of sequence alignments
  • sequence similarity searching
  • phylogeny reconstruction; and microArray analysis - statistical and clustering methods

Students will learn why a small number of model organisms are used to study development due to their convenience amenable to experimental manipulation or genetic analysis. An overview of the basic stages of development: fertilisation, cleavage, gastrulation, neurulation and organogenesis.

The following key developmental concepts will be covered:

  • cell fate
  • determination and specification
  • genetic control and gradients (morphogens)
  • pattern formation - body plan, polarity, germ layers, morphogenesis, cell differentiation; and the role of maternal factors
