Bioinformatics: Genomes and Algorithms

Description

About the Course

In this course, you will discover how computer science supports the interpretation of the text of genomes.
Running the adequate programs, a computer may produce predictions on
the location of the thousands of genes in a living organism and the
functions of the proteins these genes code for.

You are not a biologist? Attending this course, you will be
introduced to several entities and processes involved in the
interpretation of the genomic texts: cell, chromosome, DNA, genome,
genes, transcription, translation, proteins and many more.

You are not a computer scientist? This course is also an
introduction to algorithms on character strings: pattern searching,
sequence similarity, Markov chain models, or phylogenetic tree
reconstruction are some basic algorithms which are implied in genome
sequence analysis and will be explained.

You are neither a biologist nor a computer scientist? This
course is a great opportunity to a joint approach to genomics and
algorithmics, or if you prefer, to algorithmics and genomics.

Pre-Requisites

A scientific culture will make easier the understanding of the notions studied.
