Frog eggs help researchers understand repair of DNA damages

The DNA replication process in which cells divide to create new cells also triggers repair of DNA damage, researchers from the University of Copenhagen report in a new study. The researchers studied extracts from frog eggs, ...

Researchers unravel mystery of how, when DNA replicates

A team of Florida State University researchers has unlocked a decades-old mystery about how a critical cellular process is regulated and what that could mean for the future study of genetics.

Could villains clone themselves to take over the world?

If asked about clones, most people think of evil sci-fi characters. However, in real life, the word "clone" often has broader, far more positive applications. Just as office workers replicate documents by using copy machines, ...

Unveiling the mechanism protecting replicated DNA from degradation

Researchers from Tokyo Metropolitan University and the FIRC Institute of Molecular Oncology (IFOM) in Italy have succeeded in depleting AND-1, a key protein for DNA replication, by using a recently developed conditional protein ...

Researchers discover key mechanism of DNA replication

Researchers from Osaka University in Japan have uncovered a key control mechanism of DNA replication with potential implications for better understanding how cells maintain genetic information to prevent diseases or cancer.

Finding the proteins that unpack DNA

A new method allows researchers to systematically identify specialized proteins that unpack DNA inside the nucleus of a cell, making the usually dense DNA more accessible for gene expression and other functions. The method, ...

Molecular brake on human cell division prevents cancer

Researchers at Karolinska Institutet, Sweden, and the University of Sussex, England, have discovered that the process of copying DNA generates a brake signal that stalls cell division. This molecular brake ensures that the ...
