Scientists compare rat genome with human, mouse

...e researchers reported that, at approximately 2.75 billion base pairs, the rat genome is smaller than the human genome, which is 2.9 billion base pairs, and slightly larger than mouse genome, which is 2.6 billion base pairs. However, they al...

Molecular midwives hold clues to the origin of life

...ar to RNA and DNA first appeared on Earth around 4 billion years ago. Our theory is that small, simple molecules acted as templates for the production of the first RNA-like molecules. Many of these small molecules, or molecular midwives, would have worked together to produce RNA by spontaneously mixing and a...

NIST-led research de-mystifies origins of 'junk' DNA

... their relatives) diverged from bacteria roughly 2 billion years ago (the "introns-late" view). Bacterial genomes lack introns. Although the study did not attempt to propose a function for introns, or determine whether they are beneficial or harmful, the results appear to rule out the "introns-early" view. ...

As obesity skyrockets, Joslin Diabetes Center urges action to stem the tide of type 2 diabetes

... "Statistically, adults in the U.S. have gained 2 billion pounds over the past decade, which is an average of one pound per year per person. This is true for both men and women," says C. Ronald Kahn, M.D., President and Director, Joslin Diabetes Center. "For every one pound increase in weight, there is a 3...

Sequencing project results in six-fold reduction of effective size of maize genome

At about 2 to 3 billion base pairs, the maize genome is estimated to be 20 times larger than Arabidopsis, an experimental plant that is the first plant genome to be completely sequenced. However, maize probably has only twice as many genes as Arabidopsis. The rest of the m...

Duke study gives first worldwide measure of sea turtle casualties by longline fishing
