Females have one active X chromosome and one dormant X chromosome in each cell. But a study suggests that genes on the ...

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

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. They determine the ...

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

Who were our earliest ancestors? The answer could lie in a special group of single-celled organisms with a cytoskeleton similar to that of complex organisms, such as animals and plants.

Furthermore, the constructs often attached to natural chromosomes, potentially disrupting the host cell’s genome. In the new study, researchers at the University of Pennsylvania circumvented this ...

Hibernating dwarf lemurs can stay in this cold, standby state for about a week before they have to briefly warm up, and ...

Telomeres, the protective caps at the ends of chromosomes, play a key role in aging and cancer prevention. Over time, these structures naturally shorten, signaling aging cells to stop dividing -- a ...

which is necessary to ensure the cell does not end up with two identical copies after removal, but instead has one from each parent. The authors were able to remove duplicate chromosomes from both ...

HIV-1 Vif induces a unique and prolonged pseudo-metaphase arrest by disrupting phosphatase feedback regulation at the kinetochore.
