In the Bacterial World, Genetic Messengers Work Close to Home

(PhysOrg.com) -- In a fundamental shift in the view of how bacteria proliferate and survive, Yale scientists report online June 20 in the journal Nature that most of the genetic action within a cell takes place close to home.

Histone H1 regulates gene activity throughout the cell cycle

A protein that helps pack DNA into the cell nucleus has an important role in regulating gene activity, scientists report. The researchers found that the protein, histone H1, also takes part in the formation of ribosomes, ...

DksA polices the intersection of replication and transcription

DNA replication, the process by which a strand of DNA is copied during cell proliferation , and DNA transcription, the process by which the message in the DNA is translated into messenger RNA, involve the same "track" or ...

Paper wasps and honey bees share a genetic toolkit

They are both nest-building social insects, but paper wasps and honey bees organize their colonies in very different ways. In a new study, researchers report that despite their differences, these insects rely on the same ...

Detecting Our Martian Cousins

The iguanas of the Galapagos Islands have evolved many unique characteristics due to their isolation from mainland iguanas. Because they can't swim long distances, biologists believe that the first Galapagos iguanas arrived ...

Importance of different cell types underestimated

Choosing the right cell type is particularly important in genetic studies. This is apparent from research published on 16 October in PLoS Genetics. Dutch researcher Alice Gerrits has shown how variations in the genome can ...

Researchers find candidates for new HIV drugs

While studying an HIV protein that plays an essential role in AIDS progression, researchers at the University of Pittsburgh School of Medicine have discovered compounds that show promise as novel treatments for the disease.
