A large international team of researchers is claiming to have at last sequenced the entire human genome. Collectively, the team is known as the Telomere-to-Telomere (T2T) Consortium, and they have written a paper describing ...
All the cells of an organism share the same DNA sequence, but their functions, shapes or even lifespans vary greatly. This happens because each cell "reads" different chapters of the genome, thus producing alternative sets ...
