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 in a new study. In a new paper published in Nature Communications, an ...

Enzymes that cut DNA at specific sites are called endonucleases; these enzymes play many roles in genomic replication, fidelity, and defense. The initial discovery of restriction endonucleases in the ...

Scientists at the Francis Crick Institute, in collaboration with Artios, have identified how an enzyme involved in DNA repair (POLQ), becomes vital to the survival of certain cancers, if the cancer ...

A new study on genetic sequencing finds that DNA replication is not as accurate as was previously thought, which could impact a range of fields, from medicine to the study of evolution. DNA ...

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 human genome consists of 3 billion base pairs, and when a cell divides, it takes about seven hours to complete making a copy of its DNA. That's almost 120,000 base pairs per second. At that ...

Research led by the Max Planck Institute for Biology of Aging in Cologne reports that misincorporation of ribonucleotides ...

Researchers have come one step closer to unlocking the potential of synthetic DNA, which could help scientists develop never-before-seen proteins in the lab. The genetic alphabet contains just four ...

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, ...
