Finally! The first complete human genome What does it mean?

The operating manual of a human being is written in each of its cells, in a DNA molecule about two meters long, folded in an unimaginable way with the instructions to transmit a thought or generate any movement. The first completely complete reading of a person’s DNA has revealed an unknown world of redundant sequences, but it is precisely these repeated stretches in a human’s DNA that help make it unique.

The complete genome will allow scientists to analyze how DNA differs between people and whether these genetic variations play a role in disease. Until now, only 92% had been read, in which 8% of the pieces had yet to be fitted, too repetitive to find their place. Advances in technology have now made it possible to bring order to those redundant sections.

The complete genome of a human is a text of 3.055 million letters in which each letter is simply the initial of a chemical compound with different amounts of carbon, hydrogen, nitrogen and oxygen. The first complete genome of a person adds 200 million letters to the human being and corrects thousands of errors in the current reference sequence.

The DNA of a cell is divided into 46 packages, called chromosomes, which in turn are divided into sections, called genes. Some of these genes are instructions for making proteins, like some hormones or the antibodies that defend us from viruses. The complete genome includes 99 genes apparently linked to proteins, hitherto unknown, and another 2,000 presumed genes that will have to be studied in detail.
