DNA – Sequencing

Нуклеотидын дараалал тогтоох ДНХ секвенсинг 

4 төрлийн нуклеотидын тусламжтайгаар ДНХ-ийн нуклеотидын дарааллыг тодорхойлж болно. Үүнийг секвенсинг гэж нэрлэнэ.  Одоо секвенсингийг 2 аргаар хийж байна.

Секвенсингийн талаархи зургуудыг үзнэ үү?      Максим – Гилбертийн арга- Энэ арга нь секвенсинг хийхдээ дан хэлхээний аль нэг төгсгөлийг тэмдэгт атомаар \ голдуу 32Р-ээр\ тэмдэглэнэ. Сангерийн арга. Химийн хорт бодис хэрэглэдэггүй мөн автоматжуулж болдгоороо давуу.    DNA Sequencing: The Chain Termination Method (Sanger Method)  ,

The Human Genome Project (HGP) was an immense international enterprise: probably the biggest biological experiment yet attempted. Researchers worked together to read the entire sequence of the DNA letters (bases) in the human genome – more than 3,000,000,000 of them. The ‘gold standard’ sequence was announced in 2003 and published in 2004.

The Cassiopeia Project is an effort to make high quality science videos available to everyone. If you can visualize it, then understanding is not far behind.
Code for Life: Beginning more than three and a half billion years ago, a tiny, primitive molecule encoded instructions deep within itself. Then it passed these instructions on to its children, who passed it to their children and so on – all the way down through time to all living things today.

The human genome, written in a code of just four letters, tells us who we really are – and that generates many questions!

Is this process of natural selection coming to an end? Should we choose the best that is in us for our children? If so, who gets to decide what is meant by “the best that is in us”?

From amino acids in space to human genes in corn … THIS is the story.
