A primer for phylogenetic data gathering

This seminar is offered to undergraduate students (mainly in their sophomore or junior year) interested in DNA sequencing and phylogenetic analysis as a tool to reconstruct evolutionary histories. It is specifically targeted to complement the activity of students who joined or plan to join a laboratory to work with DNA extraction and sequencing.

The seminar will allow the participants to understand and become independent in the complete process of phylogenetic data collection: the rationale of the lab techniques, (including DNA extraction, PCR, sequencing) and their troubleshooting; the manipulation and preliminary analysis of sequence alignments and the retrieval and upload of sequences to GenBank. Some basic theoretical background will be provided to understand broad evolutionary and cladistics concepts. Some of the sessions will require the student to bring a laptop to try and have some practice with different phylogenetic softwares. The seminar will be completed with paper discussions and a final invited talk.

Duration: 1 credit (13 sessions of 50 minutes)

Location and time: Wednesdays from 4.40 to 5.30PM. PBB (3rd floor conference room)

Prerequisites: BIOL1107 and BIOL1108/BIOL1110
