Bioinformatics
Lecturer: Dr P. Liò
No. of lectures: 12
Aims
This course focuses on algorithms used in Bioinformatics and System Biology. Most of the algorithms are general and can be applied on multidimensional and noisy data from other fields. All the necessary biological terms and concepts useful for the course and the examination will be given in the lectures.
Lectures
- Introduction to Bioinformatics. Primer on molecular
biology and ``omics''. Open problems and types of data.
- Sequence alignment I. Dynamic programming. Global and
local alignment algorithms. Scoring matrices.
- Sequence alignment II. Block alignment and four Russians
speedup. Multiple alignment.
- Database search. Comparing a sequence against a
database. Blast family, PatternHunter, Using spaced seeds.
- Algorithms for evolutionary trees I. Parsimony methods.
- Algorithms for evolutionary trees II. Distance methods.
- Algorithms for evolutionary trees III. Maximum Likelihood
methods; bootstrap test.
- Information theory. Markov properties of genome sequences.
- Applications of Hidden Markov Models in Bioinformatics.
Examples on gene and protein structure prediction.
- Microarray data analysis. Steady state and time series
microarray data. Clustering methods.
- Introduction to system biology I. Algorithms for generating
genetic networks from microarray data. Identifying regulatory
elements using microarray data.
- Introduction to system biology II. Analysis of Genetic and
biochemical networks; Gillespie family of algorithms.
Objectives
At the end of this course students should
- understand Bioinformatics terminology
- be able to work with with bioinformaticians and biologists
- have some experience of the data used in Bioinformatics
- master the most important algorithms in the field
