In this preprint, scientists from the Telomere-to-Telomere (T2T) Consortium, an international collaboration of around 30 institutions, reported the most complete sequencing of the human genome until now.
They have, in the process, discovered over a hundred new genes that code for proteins. The total size of the genome they have sequenced is close to 3.05 billion base pairs.
This adds 200 million base pairs to the last draft of the human genome that was published in 2013.
The results come with the caveat that about 0.3% may still have errors, and that among the sex chromosomes, only the X chromosome has been sequenced.
