Scientists at EMBL have captured how human chromosomes fold into their signature rod shape during cell division, using a ...

Cytologists had been studying chromosome behavior since the late 19th century. Why did it take until 1956 to figure out the correct human chromosome number, thanks to Joe Hin Tjio and Albert Levan?

Humans inherit one set of chromosomes from their mother and a second set from their father. In total, most human cells contain 46 chromosomes with 22 pairs of autosomes, or non-sex chromosomes ...

But it might also put us at risk for uniquely human brain disorders. The study appears in Nature. The research focused on parts of chromosomes known as human accelerated regions (HARs), which have ...

Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves. For ...

An individual’s growth and development is affected by the genes they inherit from their parents. An example of a human chromosome mutation is when a child inherits an extra copy of chromosome 21.

Human-accelerated regions (HARs) in chromosomes help human neurons grow multiple neurites. When HARs were added to artificial chimpanzee neurons, as seen on the right, they grew extra neurites, ...
