Scientists discover that women's second X chromosome awakens later in life, expressing genes that protect the brain from ...

which reside in the middle of the chromosomes; transposons that can target the ends are less likely to disrupt an essential ...

UCSF researchers may have discovered how the female brain remains resilient in aging, answering an age-old question of how ...

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

the function of all eukaryotic centromeres has been strongly conserved during evolution. This article focuses on the centromeres of mammalian chromosomes, particularly those in humans. Much of ...

The effect of having only maternal X chromosomes appeared specific to brain function. Looking deeper into the brain cells themselves, the researchers discovered that neurons primarily using the ...

Greenland sharks are thought to have lifespans that can reach 400 years. Building upon previous work, University of Tokyo-led ...

In the absence of DDM1 and RNAi, this TE doesn’t produce small RNAs, so the centromere is not methylated. These mutants also had few epigenetic tags on their histones, which contribute to the ...

A test on lab mice may have helped scientists in California debunk a theory that part of the make up of genetics in females ...

Cytoplasmic flows guide chromosome positioning during embryogenesis. During the first stages of animal embryo development, the egg cell undergoes multiple divisions without growin ...
