What happened?However, the large chunk that has been sequenced contains versions of several of the same genes that are found in the modern human Y chromosome. In modern humans, a Y chromosome gene called SRY ...
Humans have about 20,000 coding genes in total. Some chromosomes have more genes than others. About 98% of human DNA does not code for anything. Introns make up about 24% of your DNA. These are ...
It’s not clear why these backups have evolved. The new Y chromosome sequences could spell change for metagenomics research, which involves sequencing microbial genomes. Human DNA contaminants often ...
