Maryland: An international team of geneticists, after nearly twenty years of effort, has finally completed 100% mapping of the human genes. Which, of course, made the video an overnight sensation.
It should be noted that the global "Human Genome Project" was started in 1990 under which a draft map of the human genome was presented in June 2000.

By April 2003, when the project was completed, mapping of about 92 parts of the human genome had been completed. That is, 8% was still left, which was very difficult for experts to read.
These parts of the human genome are called "heterochromatic" which are located on the edges (telomeres) of chromosomes and in the middle (centromers).
The heterochromatic part of the human genome has a lot of repetition of the same "DNA" which made it extremely difficult to read.
Meanwhile, in 2001, various research institutes launched a new global project called the Telomere to Telomere Consortium (T2T Consortium), which aims to move every human chromosome from one telomere to the other. "Complete" (ie, including telomeres and centromeres) and was to be read with complete accuracy.
The technologies of genetic sequencing and gene mapping have become more and more advanced. And this work continued slowly.
Now, in the latest issue of the research journal "Science", the T2T Consortium has presented a 100% complete and accurate map of the human genome, which is available online for free to the whole world.
