When the Human Genome Project was declared completed in 2003, it had mapped 92% of genes, with the rest remaining a mystery for nearly two decades due to technological limitations. Now, scientists have finished sequencing the other 8%, and the human genome has finally been fully sequenced. Almost 100 scientists from the Telomere-to-Telomere (T2T) Consortium collaborated on the project to map the entire human genome. The additional 8% that was sequenced accounts for 400 million new letters added to the existing sequenced DNA -- enough for an entire chromosome, as CNN reported. The additional genes are very important for adaptation,...
