The Gene Ontology (GO) project is a collaborative effort to address the need for
consistent descriptions of gene products and their function. GO is organized in three
different sections, biological process, molecular function and cellular component.

In this seminar we will get to know two friendly web applications used to analyze
functional enrichment in gene lists.
DAVID (http://david.abcc.ncifcrf.gov/) is an online bioinformatics resource that provides
functional interpretation of large lists of genes derived from genomic studies by integration
of GO terms, pathways, protein domains and more.
GO Tree Machine (http://bioinfo.vanderbilt.edu/gotm/) uses only GO hierarchies for its
analysis and the results are showed as an expandable tree for browsing the GO hierarchy.

We will show how to import data, how to perform statistical analysis indicating terms with
relatively enriched gene numbers and how to interpret the results suggesting biological areas of interest.
