Scientists have discovered that a protein once thought to simply help load a factor necessary for the copying of DNA, actually plays a key role in ensuring fast and reliable replication—an insight ...

Retrotransposons are sequences of DNA in animal genomes that can replicate and reinsert themselves back into the genome. Experiments in flies and other model systems reveal that retrotransposons ...

A new study reveals that certain locations of DNA are copied faster than others, which could also have an effect on mutation rate. Cell division is fundamental for life, allowing organisms to grow, ...

Researchers have identified an alternate method to study changes during the DNA replication process in lab settings using genetically modified yeast. The new approach offers a clearer window than ...

BERKELEY, CA -The molecular machinery that starts the process by which a biological cell divides into two identical daughter cells apparently worked so well early on that evolution has conserved it ...

A protein that prepares DNA for replication also prevents the replication process from running out of control, according to a new study. The work solves a mystery that has long puzzled biologists. A ...

Every person starts as just one fertilized egg. By adulthood, that single cell has turned into roughly 37 trillion cells, many of which keep dividing to create the same amount of fresh human cells ...

As cells divide, they must copy all of their chromosomes once and only once, or chaos would ensue. How do they do it? By Amber Dance/Knowable Magazine Published Jul 7, 2023 6:00 PM EDT This article ...

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...
