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 ...

DNA, often called the blueprint of life, is built from four chemical building blocks known as deoxy-nucleoside triphosphates ...

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 ...

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 ...

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 ...

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 ...

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 ...
