This week, the “Innovations” program touched on how scientists have made an important step in understanding the “human genome,” by revealing the mystery of the mysterious “Y” chromosome, found in males, in an achievement that could help direct research related to infertility in men, according to what was published. Reuters. The researchers announced the first complete sequence of the Y chromosome, which is one of the two sex-determining chromosomes and is transmitted exclusively from father to male children. Genes in the Y chromosome help control important reproductive functions, including sperm production. It also plays a role in genetic predisposition to cancer and its severity. But this chromosome has proven difficult to identify, due to its exceptionally complex structure. Karen Mega, a professor of biomolecular engineering at the University of California at Santa Cruz, who participated in the study, says that this complete sequence of the Y chromosome provides the first complete look at its code, as it reveals more than fifty percent of its length, which was missing in genome maps. previous human.
