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 ...

Chromosomes are masters of organization. These long strings of DNA fold down into an ensemble of compact structures that keep needed parts of the genome accessible while tucking away those that aren't ...

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 ...

As the cell proceeds through the stages of cell division (from left to right: interphase, prometaphase, metaphase, and anaphase), chromosomes become progressively more compact through a combination of ...

Over the past two decades, researchers have learned that DNA inside the cell nucleus naturally folds into a network of ...

In a breakthrough that could boost de-extinction efforts, scientists have determined the 3D structure of a woolly mammoth's genome from a 52,000-year-old piece of freeze-dried skin. When you purchase ...

The Y chromosome is inherited only through the paternal line. Sons receive their Y chromosome exclusively from their father.

An international research team has generated the first truly complete sequence of a human Y chromosome, the final human chromosome to be fully sequenced. The new sequence, which fills in gaps across ...
