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 ...

Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies ...

Enzymes, which are crucial to controlling how cells replicate in the human body, could be the very ingredient that encourages DNA to spontaneously mutate -- causing potentially permanent genetic ...

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified in a new study. In a new paper published in Nature Communications, an ...

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 ...

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 ...

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 ...

A protein that prepares DNA for replication also prevents the replication process from running out of control, according to a new study by Weill Cornell Medicine researchers. The work, published Jan.

A new study from Karolinska Institutet, published in Nature Communications, reveals that cyclin-dependent kinases (CDK) ...

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 ...
