It has long been thought that two enzymes, the kinases CDC7 and CDK2, are both needed to trigger DNA replication in mammalian cells. This view is challenged by evidence that offers a revised view of ...

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 ...

What is DNA, and how does it work? You don't need a degree in genetics to understand. Here, we'll give an overview of DNA and ...

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 ...

Inside every cell, a finely tuned metabolic network determines when to build, recycle, or stop producing essential molecules.

The function of an enzyme, critical to most forms of life, has been revealed. The function of an enzyme, critical to most forms of life, has been revealed. A research team, led by the John Innes ...

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, ...

The nucleus has historically been considered to be metabolically inert, importing all its needs through supply chains in the cytoplasm. Now, a new study by researchers at the Centre for Genomic ...

New research from the University of Wisconsin–Madison reveals that dysfunction in a protein essential to maintaining ...

DNA is the molecular basis of heredity, the inherited traits that pass between generations in a person's family tree. Embodied in the sequence of base pairs, DNA carries information between ...
