Researchers at Tulane University School of Medicine have discovered that if animal cells gain an extra set of chromosomes, a condition known as polyploidy, they activate a stress signaling pathway ...

Polyploid cells (green, indicated with arrows) migrate into the surrounding tissue of a fruit fly larva. Researchers at Tulane University School of Medicine have discovered that if animal cells gain ...

The Atlas blue butterfly, also known as Polyommatus atlantica, has been genetically confirmed as having the highest number of chromosomes out of all multicellular animals in the world. This insect ...

One of the biggest challenges in cancer research is understanding why some tumor cells become especially aggressive, invasive and resistant to treatment. Scientists have increasingly linked these ...

Hermit crabs have the most chromosomes of any animal, with 254. Chromosomes carry genetic information in the form of DNA. Genes located on autosomes determine the inheritance of physical traits. Sex ...

It’s official: the animal with the highest number of chromosomes is the Atlas blue butterfly, boasting a record 229 pairs. This is a pretty unusual finding since many of its closest relatives have ...

For successful cell division, chromosomal DNA needs to be packed into compact rod-shaped structures. Defects in this process can lead to cell death or diseases like cancer. A new study has shown how ...

Cephalopods may have the oldest sex chromosomes of any animal, according to a new discovery in the octopus genome. That's a big deal given that scientists didn't know until now if these oddball ...
