Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from ...

Scientists have identified key changes to both chromosome structure and gene expression that affect stem cell function during aging. Using fruit flies, they found that these changes led to stem cell ...

Translocations are chromosomal “cut and paste” errors that drive many lymphomas, a type of blood cancer and the sixth most common form of cancer overall. This includes mantle cell lymphoma, a rare but ...

Aging men often lose the Y chromosome in a growing number of their cells—and it may be far more dangerous than once believed.

DNA can also be demethylated, either through passive or active processes. Passive DNA demethylation occurs when the methylation pattern is not replenished during DNA replication and gradually ...

In back-to-back studies published in Nature, researchers from Purdue University and Columbia University report a naturally ...
