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

Each eukaryotic chromosome is composed of DNA coiled and condensed around nuclear proteins called histones. Humans inherit one set of chromosomes from their mother and a second set from their father.

Indeed, when the very first mammals evolved between 100 and 200 million years ago, they didn't have sex chromosomes at all, ...

For successful cell division, chromosomal DNA needs to be packed into compact rod-shaped structures. Defects in this process ...

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

Human biological sex is determined by the sex chromosomes X and Y. In most cases, females possess two X chromosomes, while males have one X and one Y. However, there is some evidence that the Y ...

About 50 percent of Cohanim in both Sephardic and Ashkenazic populations have an unusual set of genetic markers on their Y chromosome. What is equally striking is that this genetic signature of ...

set out to solve this problem. Beckwith and colleagues used a method to gently remove one strand of DNA in cells at various stages of cell division, keeping the chromosome structure intact.
