Scientists have completely deciphered the human genome

By 2003, the international Human Genome Project had deciphered 92% of the human genome.

Then recently, in the spring of 2022, an international team of researchers from Rockefeller University (USA) sequenced the remaining 8% of the human genome. Resultingly, the human genome is now 100% deciphered, enabling scientists to finally understand why several diseases, such as cancer, arise and how to treat or prevent them.

The 92% of the genome deciphered back in 2003 contained information about the euchromatin (the largest part of the genome, rich in genes, creating RNA for further translation into protein). This part of the genome was also loosely packed, unlike the last 8%, a tangled ball of repeating heterochromatin. These sites are located in the telomeres and centromeres of the chromosomes and generally do not produce protein.

As a result, scientists have added another 200 million pairs to the previously discovered bases from which previously unknown DNA sequences will subsequently get assembled. Consequently, the complete human genome will also be named T2T-CHM13.
