Close to two decades after the Human Genome Project (HGP) gave us our first glimpse of the human genome, researchers have now filled in the gaps to deliver the human genome sequence in its entirety, all the three billion bases, Science Daily reported. The HGP revolutionised our understanding of genetics and opened doors to identifying the causes of many disease conditions. However, more than 15 years after the project was completed scientists had access to only 92 percent of the human genome. While the missing gap consisted largely of repeat sequences in the telomeric region of the chromosome, it accounted for the absence of one chromosome worth of genetic data.
