Microbe's genome reveals insights into ocean ecology

...acteria account for an estimated 15 percent of the production of new microbial cells in the ocean. The Nature paper's first author, Mary Ann Moran, says the DNA sequence sheds new light on ecological strategies that sustain microbial life in the world's oceans. "This genome is especially sig...

Although MeCP2 is expressed throughout the body, RTT is a disorder of the central nervous system and therefore it is ...

NPP data, though, are not as important as are the changes in the type and distribution of vegetation as an area transitions ...

Analysis of where the genes for the fluorescent proteins ended up when inserted into the B-cell genome revealed that initially many were integrat...
