What is the Human Genome Project?

10/02/2016 Σχολιάστε

Begun formally in 1990, the U.S. Human Genome Project was a 13-year effort coordinated by the U.S. Department of Energy and the National Institutes of Health. The project originally was planned to last 15 years, but rapid technological advances accelerated the completion date to 2003.

In August 1996, at St. Barnabas Medical Center in Livingston, N.J., a 39-year-old mechanical engineer from Pittsburgh named Maureen Ott became pregnant. Ott had been trying for almost seven years to conceive a child through in vitro fertilization. Unwilling to give up, she submitted to an experimental procedure in which doctors extracted her eggs, slid a needle through their shiny coat and injected not only her husband’s sperm but also a small amount of cytoplasm from another woman’s egg. When the embryo was implanted in Ott’s womb, she became the first woman on record to be successfully impregnated using this procedure, which some say is the root of an exciting medical advance and others say is the beginning of the end of the human species.

The Path to Reading a Newborn’s DNA Map

By ANNE EISENBERGFEB. 8, 2014, The New York Times

 

What if laboratories could run comprehensive DNA tests on infants at birth, spotting important variations in their genomes that might indicate future medical problems? Should parents be told of each variation, even if any risk is still unclear? Would they even want to know?

A Powerful New Way to Edit DNA

By ANDREW POLLACK, The New York Times, MARCH 3, 2014

     

In the late 1980s, scientists at Osaka University in Japan noticed unusual repeated DNA sequences next to a gene they were studying in a common bacterium. They mentioned them in the final paragraph of a paper: “The biological significance of these sequences is not known.”

Now their significance is known, and it has set off a scientific frenzy.

Excavation in the Denisova cave in Siberia.

By CARL ZIMMER, The New York Times Published: December 18, 2013

Scientists have extracted the entire genome of a 130,000-year-old Neanderthal from a single toe bone in a Siberian cave, an accomplishment that far outstrips any previous work on Neanderthal genes

23-DNA-information

Ατέλειωτος ο κόσμος του DNA, τα γονίδια απέραντο πεδίο της πιο ελκυστικής στις ημέρες μας έρευνας, διαρκείς ελπίδες και απίθανα όνειρα των επιστημόνων για ένα νέο “βιολογικό παράδειγμα”.

Ένα οδοιπορικό στον επιστημονικό και … κοινωνικό κόσμο του DNA. Περιλαμβάνει αποδελτιώσεις (προφανώς προσωπικής επιλογής) και αρθρογραφία, ελληνική και αγγλόφωνη.
