Each human cell contains 23 pairs of chromosomes that carry DNA within their nucleus. The X and Y chromosomes, commonly referred to as the sex chromosomes, are one such pair.

The research focused on parts of chromosomes known as human accelerated ... of HARs in artificial neurons derived from human and chimpanzee cell lines. The human and chimpanzee genomes are 99% ...

Cells use many complex genetic repair backup systems to fix DNA damage and remain healthy throughout their lives.

The nucleus of each human body cell contains 46 chromosomes. Each chromosome contains about 1000 genes. There is enough DNA in all the cells in a human body to stretch to the sun and back again ...

To prepare the 46 chromosomes of a human cell for transport to the daughter cells during cell division, each chromosome forms a compact X-shaped structure with two rod-like copies. How the cell ...

For this, the cell must duplicate its DNA -- its genome -- and segregate it equally into two new daughter cells. To prepare the 46 chromosomes of a human cell for transport to the daughter cells ...

A new study from Weill Cornell Medicine provides insights into how cells maintain the tiny end caps of chromosomes as they ...

as well as genetic mutations that lead to human diseases such as cancer. “While we and many others have contributed to the general understanding of how the genome is folded inside chromosomes during ...

For chromosomes to form the iconic X-shape that ensures the accurate passing of genetic information during cell division, a ...
