Researchers in Japan have discovered that the local DNA motion inside of human cells remains steady throughout interphase, where the cell grows and replicates its DNA for cell division. The study suggests that this steady-state ...

The entire genomic material of a cell must be packed into a tiny cell nucleus in such a way, that on the one hand, it can be stored in an organized manner and, on the other hand, it can be transcribed, duplicated or repaired ...

When cells reproduce, the internal mechanisms that copy DNA get it right nearly every time. Rice University bioscientists have uncovered a tiny detail that helps understand how the process could go wrong.

Healthy human cells have two (diploid) sets of chromosomes. However, it may also happens that cells have a tetraploid (quadruple) set. Usually, they do not divide further and die, but some cells can escape this fate. An international ...

When something goes wrong during DNA replication, cells call their own version of 911 to pause the process and fix the problem—a failsafe that is critical to maintaining health and staving off disease.

Beneath the SARS-CoV-2 membrane and its spikes lurks a squiggle of genetic material, or RNA, enveloped by a protein that acts like bubble wrap to protect the genetic material. This protein also acts as a "hotbed" for multiple ...
