After completing the module the student:|
- Has knowledge on the evolution of protein interactions and pathways.
- Is able to use online and local bioinformatic tools to collect homologs from relevant species and construct a phylogenetic gene tree
- Is able to root and interpret phylogenetic tree of genes;timeduplications of genes relative to the species tree, define orthologs and paralogs within the gene treeits origin.

- Understands the compuational pipeline for large scale bioinformatics analysis in papers describing genome evolution
- Has knowledge about the different large scale methods to create orthology databases such as COG, ENSEMBL COMPARA, PANTHER, ORTHOMCL, and is able to browse a selection of them.
- Has knowledge on the computational piplelines that have been used to recognizing genome duplications and consequences of genome duplications. And knows where most important genome duplications have taken place in the history of life.
- Is able to intepret analyis databases containing information on genome duplications and recognizing potential genomie duplication events in gene trees.

- Understands the importance of key genomes in infering molecular evolutionary events.
Currently, molecular biology is generating information on the molecular properties of cells and organisms at an incredible pace. For example, we know the complete genome sequence of an enormous and rapidly increasing number of species. Not only do these high-throughput experiments generate a complete view of the genetic information of cells, other techniques measure the level of expression of all genes at the same time or measure all the interactions between all the proteins present in a cell. Bioinformatics is obviously needed for the storage and primary analysis of these huge volumes of biomolecular data. More interestingly, the data uniquely allows bioinformatics to make biological discoveries that were not possible until now. This course introduces the concepts and approaches required to make evolutionary biological discoveries in this genome-scale data and presents examples of interesting pieces of biology that have been discovered using bioinformatics. Topics to be discussed include genome evolution (as opposed to single genes), and the origins of the eukaryotic cell.|
The following subjects are discussed in the course:
1. Sequence homology, Protein domains
2. Gene trees and orthology
3. Genome evolution: evolution of the presence of genes, evolution of gene order
4. Formalizations of gene function (e.g. Gene Ontology)
5. Introduction to high-throughput (HTP) techniques such as micro-array, ChIP-on-chip and yeast-2-hybrid
6. Use of these HTP data to study evolution of function
7. Origin of Eukaryotes, endo-symbiosis, explosion of gene duplicates
8. Genome Evolution: Genome duplications
