Gapless Telomere to Telomere human genome (T2T-CHM13) now available

On April 1, 2022, Science published the first complete sequence of a human genome, known as T2T-CHM13. This notable scientific achievement comes two decades after the first human genome release from the Human Genome Project and offers an in situ look at biologically important regions, such as centromeres, telomeres, and segmental duplications, that were previously … Continue reading Gapless Telomere to Telomere human genome (T2T-CHM13) now available
