“Great progress”. The Y chromosome has finally been deciphered

This scientific result is breathtaking. Small and 2.5 times smaller than the X chromosome (twice in females and twice in males), the Y chromosome is finally deciphered. Its complete sequence is carried out according to two publications published in Nature. This is a scientific and technical feat that opens up new fields for genetics and certain treatments.

First of all, it is a long scientific project. The complete sequence of the Y chromosome completes the complete map of the human genome, the support of life, made up of 3.1 billion base pairs (where each base is symbolized by one of the four letters A, T, C, or G). The sequence of these letters characterizes the genes carried by each chromosome. This international project began more than thirty years ago, and the first, incomplete version of the genome, the Human Genome Project, was published in 2003. In 2018, a complete and accurate map project was launched by an American consortium called T2T…
