A chromosome is a single, long molecule of DNA. These highly organized structures store genetic information in living organisms. Small sections of the chromosome, called genes, code for the RNA ...

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 ...

In particular, it explains that humans have one fewer chromosome pair in their cells than apes, due to a mutation found in chromosome number 2 that caused two chromosomes to fuse into one.

Things are changeable in the aging brain, and the X chromosome clearly can teach us what’s possible.” Dena Dubal, MD, PhD The scientists created hybrid mice from two different strains of laboratory ...

In a surprise, work in mice has found that the dormant X chromosome in females can reawaken late in life and turn on genes that keep the brain healthy. UCSF researchers may have discovered how the ...
