The Human Genome Project Pieced Together Only 92% Of The DNA - Now Scientists Have Finally Filled In The Remaining 8%
THE CONVERSATION - When the Human Genome Project announced that they had completed the first human genome in 2003, it was a momentous accomplishment - for the first time, the DNA blueprint of human life was unlocked. But it came with a catch - they weren’t actually able to put together all the genetic information in the genome. There were gaps: unfilled, often repetitive regions that were too confusing to piece together. With advancements in technology that could handle these repetitive sequences, scientists finally filled those gaps in May 2021 , and the first end-to-end human genome was officially published on Mar. 31, 2022 . I am a genome biologist who studies repetitive DNA sequences and how they shape genomes throughout evolutionary history. I was part of the team that helped characterize the repeat sequences missing from the genome. And now, with a truly complete human genome, these uncovered repetitive regions are finally being explored in full for the first time
