The DNA sequence

A message is decoded

Many times a day, the DNA of an organism replicates itself. Each time, this replication occurs in the exact same way and without any error. However, sometimes a mutation may occur in the long sequence of the DNA, i.e. one base may be substituted by another. This substitution is called single nucleotide polymorphism or SNP (“snip”). The progressive accumulation of these changes constitutes the genetic identity of an organism.

The BioMuse programme implemented the PHENOREPORT, a bioinformatics tool that has automated the listing and study of a large number of SNPs in the genomes that were analysed, in order to create the genetic profile of the studied individuals.
