Thus, in her experiments, McClintock observed several fundamental properties of chromosome biology; specifically, she noticed that cells do not tolerate the presence of unprotected chromosome ends ...

The X contains more genes related to brain function than does any other chromosome. “The X chromosome may be a treasure trove of genes that influence cognition, and these could be therapeutic targets, ...

Female mammals typically carry two X chromosomes — one from each parent — and a new study suggests that the maternal X is ...

The executive order’s definitions of male and female left room for interpretation contrary to the spirit of the order.

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.

However, the large chunk that has been sequenced contains versions of several of the same genes that are found in the modern human Y chromosome. In modern humans, a Y chromosome gene called SRY ...

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.

A UCSF study reveals that maternal X chromosome expression may accelerate brain aging and cognitive decline. Female mice with ...

The epigenetic state of chromatin, gene activity, and chromosomal positions are interrelated. A research team from the IPK Leibniz Institute (IPK) and the Karlsruhe Institute of Technology (KIT) ...

Researchers at The University of Hong Kong (HKU) have made an exciting discovery about how human cells protect DNA during ...
