Analysis of Biological Sequences
FEKT-FABSAcad. year: 2017/2018
The subject provides statistical foundations and an overview of the core algorithms of sequence analysis. Topics covered will include background on probability, Hidden Markov Models, and multiple hypothesis testing. Sequence analysis algorithms will include alignment, optimal pairwise local alignment, pairwise global alignment and multiple alignment, gene finding and phylogenetic trees.
Learning outcomes of the course unit
The student will be able to:
- describe basic methods of computer processing of symbolic sequences,
- explain characteristics of DNA and protein evolution,
- describe principle of methods for construction and analysis of fylogenetic trees,
- discus advantages and disadvantages of the methods,
- explain principle of numeric conversion of symbolic biological sequences.
The student should be able to explain fundamental principles of genetics, should know basic terms and laws of molecular biology and should be oriented in basic knowledge of digital signal processing. In general, knowledge on the Bachelor's degree level is requested.

Planned learning activities and teaching methods
Techning methods include lectures and computer laboratories. Course is taking advantage of e-learning (Moodle) system. Students have to write projects/assignments during the course.
Assesment methods and criteria linked to learning outcomes
up to 40 points from computer exercises (3 tests and 1 homework)
up to 60 points from finel written exam
The exam is oriented to verification of orientation in terms of advanced processing of biological sequences, ability to design methods for sequence analysis, apply operations on sequences.
