Recently, a preprint titled “The complete sequence of the human genome” was posted in the online repository bioRxiv.
About
In this preprint, scientists from the Telomere-to-Telomere (T2T) Consortium, an international collaboration of around 30 institutions, reported the most complete sequencing of the human genome until now.
Gene Sequencing
DNA sequencing is a laboratory technique used to determine the exact sequence of bases (A, C, G, and T) in a DNA molecule.
The DNA base sequence carries the information a cell needs to assemble protein and RNA molecules.
DNA sequence information is important to scientists investigating the functions of genes.
Background
The Human genome project announced in 1990 announced a complete human genome but about 15% of it was incomplete.
Due to limitations of technology scientists were not able to piece together some of the repetitive parts of the human genome.
Recent developments
This time researchers discovered over a hundred new genes that code for proteins.
The total size of the genome they have sequenced is close to 3.05 billion base pairs.
This adds 200 million base pairs to the last draft of the human genome that was published in 2013.
The results come with the caveat that about 0.3% may still have errors, and that among the sex chromosomes, only the X chromosome has been sequenced.
