Reading DNA, backward and forward

Reading DNA, backward and forward | Biosciencia News | Scoop.it
MIT biologists have discovered a mechanism that allows cells to read their own DNA in the correct direction and prevents them from copying most of the so-called “junk DNA” that makes up long stretches of our genome.
Biosciencia's insight:

DNA, which is housed within the nucleus of cells, controls cellular activity by coding for the production of RNAs and proteins. To exert this control, the genetic information encoded by DNA must first be copied, or transcribed, into messenger RNA (mRNA).

New device can extract human DNA with full genetic data in minutes

New device can extract human DNA with full genetic data in minutes | Biosciencia News | Scoop.it

Take a swab of saliva from your mouth and within minutes your DNA could be ready for analysis and genome sequencing with the help of a new device.


Via Dr. Stefan Gruenwald
Biosciencia's insight:

The device will give hospitals and research labs a much easier way to separate DNA from human fluid samples, which will help with genome sequencing, disease diagnosis and forensic investigations.

Los avances en genética y ciencias afines junto con el desarrollo de tecnologías vinculadas, es cada vez más rápido y específico, no dejará de sorprenderme.,.

It bothers me that an American university which receives American tax dollars for funding has decided to contract with a Korean company to manufacture this amazing device. We will never solve our economic woes if we don't bring mfg back to the US.
Center for Accessible Living NKY's curator insight, May 15, 2013 5:29 PM

This should make obtaining genetic diagnosis much easier and faster.

Scientists from Australia and the United States bring new insights to our understanding of the three-dimensional structure of the genome, one of the biggest challenges currently facing the fields of genomics and genetics.
Biosciencia's insight:

Dr Tim Mercer and Professor John Mattick from Sydney's Garvan Institute of Medical Research and Professor John Stamatoyannopoulos from Seattle's University of Washington analysed the genome's 3D structure, at high resolution.

New cost-effective genome assembly process developed

New cost-effective genome assembly process developed | Biosciencia News | Scoop.it
The U.S. Department of Energy Joint Genome Institute (DOE JGI) is among the world leaders in sequencing the genomes of microbes, focusing on their potential applications in the fields of bioenergy and environment.
Biosciencia's insight:

DOE JGI researchers are part of a team that has developed what is described as "a fully automated process from DNA sample preparation to the determination of the finished genome."
