DNA replication is a complex process with many moving parts. In baker's yeast, the molecular complex Ctf18-RFC keeps parts of the replication machinery from falling off the DNA strand. Human cells ...

Every day, billions of cells in your body divide, helping to replace old and injured cells with new ones. And each time this ...

Fast-evolving DNA gives human neurons greater complexity than chimps, aiding cognition but also increasing disease risk. A ...

Cryo-Electron Microscopy Reveals Hidden Mechanics of DNA Replication, Sheds New Light on Cancer Target Mar. 10, 2025 — Researchers shed new light on G-quadruplexes, a type of secondary DNA ...

Researchers have now uncovered the role of mitochondrial transcription elongation factor in maintaining the balance between ...

Scientists found that fast-evolving DNA shaped human brain development but might also increase risks for mental disorders.

Then, during the next round of DNA replication, DNA polymerase and the DNA repair enzymes fill in the other strand. Thus, telomerase is able to both maintain and extend the length of telomeres.

Scientists have long agreed that early humans mated with Neanderthals, but a pair of recent studies have shed light on when exactly this DNA mixing occurred. Such a revelation could help ...

Genome and mutations DNA replication is carefully controlled to preserve the genetic information. However, changes in the genome do sometimes occur. These changes are known as mutations.
