UCSF researchers found that brain cells age more quickly when they rely solely on the X chromosome inherited from a female's mother, rather than the one from her father. Women inherit two X ...

The image is a time projection of mitochondria (in the cytoplasm, grey) and chromosomes (center of the cell, orange) during anaphase showing a flow pattern with vortexes. The flow pattern is aligned ...

What stands out the most about this ancient cephalopod sex chromosome is how little the chromosome has changed over time.

The octopus just revealed another one of its secrets: what determines its sex. University of Oregon researchers have ...

It took more than 50 years for Marthe Gautier to set the record straight about her discovery of the genetic cause of Down ...

Each human cell contains 23 pairs of chromosomes that carry DNA within their nucleus. The X and Y chromosomes, commonly referred to as the sex chromosomes, are one such pair.

In a nutshell Female cells randomly use either the maternal or paternal X chromosome—this study shows that relying more ...

People with shorter telomeres, the protective caps at the end of chromosomes, inside their white blood cells may be more ...

Females carry two X chromosomes, after inheriting one from each parent. In order to stop serious problems from arising, cells ...

Mitosis orchestrates eukaryotic cell division, maintaining genetic fidelity and playing a key role in development, tissue homeostasis, and cancer progression.

When a cell starts splitting into two daughter cells, its chromosomes align. The process of chromosome alignment can be likened to a high-stakes game of tug-of-war. In a healthy cell, chromosomes ...
