Biology reminder
It is estimated that only 10% of the DNA code contains useful information.
A gene is a coding sequence of DNA used by the cells. The set of genes forms the genome.
The proteins are the basic building blocks of living beings. They are composed of simpler elements called amino-acids. The assembly of these amino-acids determines the structure and therefore the function of a protein.
The protein synthesis is the result of a two-step process :
- A DNA sequence is copied by a RNA molecule.
- The RNA molecule is decoded in the ribosome to generate a protein.
