After two decades the human genome is finally finished

    Finally after two decades the human genome is finally complete. The decoding of the entire human genome took two decades to finally state that in fact this is complete. Previously, the human genome was once 'finished', in 2000, it was celebrated across the world,  unfortunately everyone found out it wasn't complete. This was due to the DNA sequencing technologies, and even after updates it was still 8% of the genome. According to the article from U.S. News "The human genome is made up of about 3.1 million DNA submits, pairs of chemical bases known by the letters A, C, G and T. Genes are strings of these lettered pairs that contain instructions for making proteins, the building blocks of life. Humans have about 30,000 genes, organized in 23 groups called chromosomes that are found in the nucleus of every cell."
    This is outstanding considering the fact that the first scientists who have completed the first ever human genome sequence did not confirm 8%. Considering the numbers of the DNA submits how much is 8% in identifying the missing pieces of this puzzle? Additionally, how did these new scientists considering on starting to find these missing pieces. Reading genes require cutting the strands of DNA into pieces hundreds to thousands of letters long. Sequencing machines read the letters in each piece and scientists try to put the pieces in the right order. That's especially tough in areas where letters repeat
    With this new piece of information can open doors in understanding human evolution even more. It could also open the door to medical discoveries in areas like: aging, neurodegenerative conditions, cancer and heart disease. Mentioning this would be that the 8% of human genome that was detect help important information of what makes human unique. Nevertheless scientists have finally been able to assemble the full genetic blueprint for human life adding the missing pieces to a puzzle nearly completed two decades ago.

  1. I remember discussing this during lecture. The researchers that worked on this project will very likely win the Nobel Prize. This is absolutely astounding, and is a historical point in genetics as it's the first time that the genome has finally been complete. I'm excited to see what information this has in store, especially for the medical community as genetics could provide an infinite amount of information.
