Microorganisms—bacteria, viruses and other tiny life forms—may drive biological variation in visible life as much, if not ...

In nature, ecosystems are tightly linked through the flow of organisms, detritus, and nutrients across boundaries arbitrarily imagined by humans. These systems are deeply in tune with seasonal ...

THERE have been several studies on the interrelation of nose and skin bacteria in unisolated groups of human beings,1 2 3 but little has been written about variations in the micro-organisms of the ...

Charles Darwin saw that random variations in organisms provide fodder for evolution. Modern scientists are revealing how that diversity arises from changes to DNA and can add up to complex ...

Cold Spring Harbor Symposium WITH thg meting held at the Long Island Biological Laboratory during July 2–12, the series of Cold Spring Harbor Symposia on Quantitative Hologyy interrupted since ...

That micro-organisms have a great capacity to vary their surface structure is well known. It is one of the reasons why it is so difficult to develop vaccines against HIV and malaria, and why new ...

However, epigeneticists including Andrew Pospisilik think mutations are responsible for only a portion of the variation present in all organisms. Epigenetic changes from molecules attaching to DNA and ...

Genetic variation describes naturally occurring genetic differences among individuals of the same species. This variation permits flexibility and survival of a population in the face of changing ...

In most organisms, the start of translation is coded by the sequence AUG. This sequence triggers the binding of tRNA that carries t. Some organisms adopt an unusual strategy to make sure the genetic ...

Microorganisms — bacteria, viruses and other tiny life forms — may drive biological variation in visible life as much, if not more, than genetic mutations, creating new lineages and even new ...
