A mixture of DNA and proteins—known as "chromatin"—sits inside every cell nucleus as a jumbled puddle of genetic information. As cells prepare to divide during mitosis, the chromatin is condensed into ...

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 ...

Researchers are gaining a new appreciation for the genes on the X and Y chromosomes and how they shape sex differences in ...

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 ...

Behavioral genetics explores how genes and environment intertwine to shape intelligence, personality, and behavior. From twin studies to genome-wide association research, scientists are uncovering how ...

In a major leap forward for genetic and biomedical research, scientists have developed a powerful new artificial intelligence tool that can predict the 3D shape of chromosomes inside individual cells ...

Across ant evolution, colonies have repeatedly split into two distinct social worlds: those ruled by a single queen and those shared among many. This difference is now linked to a supergene 1 — a ...

SEM images of male and female human aortic valve tissue samples from two healthy patients and two patients diagnosed with AVS. Scale bars, 5 micrometers. A study led by bioengineers at the University ...

The evolution of sex chromosomes influences reproductive biology and genome evolution across species. In Drosophila pseudoobscura, the Y chromosome has a distinct origin compared to Drosophila ...

Researchers have shed new light on how a type of heart valve disease -- aortic valve stenosis -- progresses differently in males and females. A study led by bioengineers at the University of ...
