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 ...

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 ...

Microtubules, the dynamic filaments that form the cell's internal scaffolding, have long been viewed as mere passive ...

In a major leap forward for genetic and biomedical research, two scientists at the University of Missouri have developed a powerful new artificial intelligence tool that can predict the 3D shape of ...

A central question in molecular biology is how cells protect their chromosomes from damage during repeated cell division. At ...

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 ...

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