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 ...

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 ...

A challenging goal in biology is to understand how the principal cellular functions are integrated so that cells achieve viability and optimal fitness under a wide range of nutritional conditions.

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 ...

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 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.
