Biologists studying the processes of evolution appear to have resolved a longstanding conundrum: how can organisms be robust against the effects of mutations yet simultaneously adaptable when the ...

Carlsberg has patented a method using digital PCR to identify specific nucleotide mutations in mutated genes. The process involves mutagenizing a pool of organisms, dividing them into sub-pools, and ...

For a long time, evolutionary biologists have thought that the genetic mutations that drive the evolution of genes and proteins are largely neutral: they're neither good nor bad, but just ordinary ...

Across the diverse biological systems discussed in this Review, the underlying principles concerning the mechanisms and dynamics of resistance development are similar. Drug resistance has emerged in ...

This goes against one of the key assumptions of the theory of evolution. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Genetic changes that ...

Whether they're damaged by injury or disease, or simply conducting the daily maintenance required for life, organisms have to make new cells. That generally requires replicating the organism's genome ...

A warmer global climate can cause mutations to have more severe consequences for the health of organisms through their detrimental effect on protein function. This may have major repercussions on ...

Mutations are the raw ingredient of evolution, providing variation that sometimes makes an organism more successful in its environment. But most mutations are expected to be neutral and have no impact ...

ANN ARBOR—For a long time, evolutionary biologists have thought that the genetic mutations that drive the evolution of genes and proteins are largely neutral: they're neither good nor bad, but just ...

DNA codes carrying instructions for creating a protein can sometimes be 'spelt' differently, although they specify the exact same sequence information to create that protein. Scientists have now shown ...

Why do we age and die? Aging, or senescence as it is sometimes called, is an inevitable progressive deterioration of physiological function with increasing age, demographically characterized by an age ...
