The improper segregation of chromosomes during cell division leads to abnormalities that disrupt the proper functioning of ...

It is a genetic condition caused when an unusual cell division result in an extra full or even partial copy of chromosome 21.

The ends of chromosomes, called telomeres, typically shorten as an organism ages. But when some fat-tail dwarf lemurs ...

Cancer researchers at Children's Medical Research Institute have discovered an "unexpected mechanism" that our cells use to ...

A study led by bioengineers at the University of California San Diego sheds new light on how a type of heart valve disease, ...

Australian researchers have identified a surprising mechanism focusing on telomeres -- protective caps at the ends of ...

A chromosome is comprised of a single DNA molecule that may be either circular or linear. The full complement of a cell s chromosomes is called the genome. Chromosome pairing and synapsis must be ...

Ten years ago, nobody knew that Asgard archaea even existed. In 2015, however, researchers examining deep-sea sediments ...

With age, telomeres -- protective caps at the ends of chromosomes -- naturally shorten, signaling ageing cells to stop dividing -- a safeguard against cancer ...

Now researchers might have uncovered a source for this resilience: the second X chromosome in female cells that was previously considered ‘silent’. Why the sexes don’t feel pain the same way ...

Why do women's brains fare better in aging than men's? A study found that the second, 'silent' X chromosome turns on in the ...
