A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified. A protein that is involved in determining which enzymes cut or unwind DNA ...

When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication ...

Tsukuba, Japan—Mitochondria are intracellular organelles that evolved from a bacterium belonging to Alpharoteobacteria, which was taken up as an endosymbiont by the common ancestor of eukaryotes.

Aging, neurological diseases and our bodies' stress response are all linked to the tiny power plants inside each cell known as mitochondria. To function properly, mitochondria must first read ...

CRISPR—Clustered Regularly Interspaced Short Palindromic Repeats—is the microbial world’s answer to adaptive immunity. Bacteria don’t generate antibodies when they are invaded by a pathogen and then ...

Researchers at the Centre for Genomic Regulation (CRG) reveal that metabolic enzymes known for their roles in energy production and nucleotide synthesis are taking on unexpected "second jobs" within ...

A new family of enzymes enables precise cuts in single-stranded DNA, offering powerful new tools for genetic engineering and expanding possibilities in biotechnology. (Nanowerk News) A few years ago, ...

Inside every cell, a finely tuned metabolic network determines when to build, recycle, or stop producing essential molecules. A central part of this network is folate metabolism, a process that ...

Many writers grouse when an editor makes a change in a story, but the consequences of changing a single word usually aren’t that dire. Not so with genetic instructions for making proteins. Even a ...
