The same genetic mutations that can trigger cancer in some tissues are relatively harmless in others. A new Yale study has identified an unlikely source of protection against some forms of skin cancer—hair follicle regeneration.

The first step in gene expression is the exact copying of a segment of DNA by the enzyme known as RNA polymerase II, or pol II, into a mirror image RNA. Scientists recognize that pol II does not transcribe RNA via a smooth ...

Transcription is a cellular process by which genetic information from DNA is copied to messenger RNA for protein production. But anticancer drugs and environmental chemicals can sometimes interrupt this flow of genetic information ...

Filamentous fungi produce powerful enzymes that break down tough plant material that can be used for biofuels and other industrial processes. But the enzymes often work too slowly for industrial use and the fungi are difficult ...

Scientists have suspected that spare parts in the genome—extra copies of functional genes that arise when genes or whole genomes get duplicated -- might sometimes provide the raw materials for the evolution of new traits. ...

In what they say was a lucky and unexpected finding, researchers at Johns Hopkins say they've discovered that male fruit flies lay down an odorant, or pheromone, that not only attracts females to lay eggs nearby, but also ...

(Phys.org)—A team of researchers from institutions in the U.K. and Switzerland has identified a protein that is heavily involved in entrainment in fruit fly brains as part of coordinating the circadian clock. In their paper ...
Plants grow upward from a tip of undifferentiated tissue called the shoot apical meristem. As the tip extends, stem cells at the center of the meristem divide and increase in numbers. But the cells on the periphery differentiate ...

Barley grown in Scandinavian countries is adapted in a similar way to reindeer to cope with the extremes of day length at high latitudes. Researchers have found a genetic mutation in some Scandinavian barley varieties that ...
