Prerequisites
Students need to understand basic principles of molecular biology and genetics. Suggested courses are Neparametrické metody (K. Kubošová) and Stochastické modely (M. Budíková).
Course Enrolment Limitations
The course is offered to students of any study field.
The capacity limit for the course is 30 student(s).
Current registration and enrolment status: enrolled: 0/30, only registered: 0/30, only registered with preference (fields directly associated with the programme): 0/30
Course objectives
After completing the course the student will be able:
- to formulate a hypothesis and to test it;
- to assemble a complete DNA sequence, using graphical output from sequencing;
- to use information available in genetic databases;
- to identify an unknown sequence by searching the genetic databases and comparing the hits with suitable BLAST algorithms;
- to evaluate the sequence identification;
- to calculate genetic distances, using suitable substitution model;
- to reconstruct phylogenetic trees, using distance methods, maximum parsimony, maximum likelihood and Bayesian inference;
- to interpret phylogenetic relationships in a sequence dataset and critically evaluate conflicting results.
