Y chromosome fully sequenced for the first time, revealing its secrets from ‘telomere-to-telomere’

In a new article published Aug. 23 in Nature, scientists with the Telomere-to-Telomere, or T2T, consortium—a group of researchers affiliated with the U.S. National Institutes of Health’s National Human Genome Research Institute—described how they used advanced DNA sequencing technology to reveal previously hidden areas of the Y chromosome.

“With the full sequence of a human Y chromosome, we now know what the Y looks like from telomere-to-telomere,” author Monika Chechova, Ph.D., a postdoc at the University of California, Santa Cruz, told Fierce Biotech Research in an email.

If you’re a bit confused by this news, you’re not alone. After all, didn’t the T2T consortium just...
