![]() Those behind the genome mapping project note that this is “a” human genome, not “the” human genome. Knowing the previously-missing slices of human DNA could help medical professionals pinpoint genetic variations that lead to certain diseases, and allow scientists better understand how humans evolved particular traits that distinguish us from our great ape ancestors. Now that we can clearly see everything, we are one step closer to understanding what it all means.” “Truly finishing the human genome sequence was like putting on a new pair of glasses. “In the future, when someone has their genome sequenced, we will be able to identify all of the variants in their DNA and use that information to better guide their healthcare,” says Adam Phillippy of the National Human Genome Research Institute, and co-chair of the consortium, in a press release. Scientists now have access to “long-read” sequencing machines that decode larger slices of genetic material at once, allowing them to fill in missing gaps accounting for roughly 400 million letters. DNA sequencing technology could only produce short fragments of genetic code, about 500 letters at a time, reports Evan Bush for NBC News. When researchers published their first draft of a human genome in the early 2000s, genetic sequencing technology was far more limited. They then employ the help of machines to read the individual letters in each snippet, which scientists try to put in the right order, according to the Guardian’s Hannah Devlin. Scientists slice the DNA into pieces ranging from hundreds to thousands of letters long. “The complete blueprint is going to revolutionize the way we think about human genomic variation, disease and evolution.”ĭeciphering a genome is a lot like putting together a puzzle. “I am thrilled that we got the job done,” Eichler says in a press release. Their work was published in the journal Science. The genome mapping effort was a collaboration of nearly 100 researchers from government, academic and private organizations, called the Telomere-to-Telomere consortium. ![]() Having a gap-free sequence of a human genome could lead to new medical discoveries and reveal clues about our evolutionary past. “Hallelujah, we finally finished one human genome, but the best is yet to come,” says Evan Eichler, a University of Washington geneticist and one of the leaders of the mapping project, in a news briefing Thursday. Now, scientists have finally finished their quest. But the blueprint was only partially complete, missing eight percent of the genes. Around 20 years ago, researchers completed a draft of the human genome: a sequence of roughly three billion letters. ![]()
