Researchers at Cardiff University have uncovered how a particularly severe form of DNA damage arises—shedding new light on ...

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 ...

Human sex chromosomes originated from a pair of autosomes, the ordinary or non-sex chromosomes that contain the majority of our genome and come in identical pairs. That ancestral pair of autosomes ...

For many years, scientists have delved into human chromosomes and the DNA they carry, studying the genetic code in each cell ...

The vast majority of cancer cells have too few or too many copies of some chromosomes, a state known as aneuploidy. But for decades, researchers have debated whether aneuploidy promotes the growth of ...

Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves. For this, the cell must duplicate its DNA—its genome—and segregate it equally ...

The loss of the Y chromosome in tumour cells is linked to poor outcomes for people with cancer 1, but this genetic alteration might also compromise immune cells that would otherwise fight the disease.

Sharks and rays have been found to have an XY sex chromosome system superficially like our own, but with its own unique features. It’s also older than that of any other vertebrate. There are lots of ...
