Females have one active X chromosome and one dormant X chromosome in each cell. But a study suggests that genes on the dormant X get "reawakened" later in life, potentially giving the brain a boost.

Defects in this process can lead to cell death or diseases like cancer. A new study has shown how chromosomes change shape during cell division. Certain protein complexes help fold DNA into ...

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

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 ...

Each human body cell contains 46 chromosomes. These can be arranged into 23 pairs. Each chromosome in a pair carries the same types of genes. The 23rd pair are the sex chromosomes: In females ...

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

When the researchers looked at human data, they found the same trend. Men who had lost more Y chromosomes were more likely to ...

The five phases of mitosis and cell division tightly coordinate the movements of hundreds of proteins. How did early biologists unravel this complex dance of chromosomes? The most obvious ...

ChromTR, a novel framework for chromosome detection in metaphase cell images, represents a significant advancement in the ...

Chromosomes that lack centromeres segregate randomly during mitosis and are eventually lost from cells. At the other extreme, chromosomes with multiple centromeres are subject to fragmentation if ...

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. They determine the ...

Instead of having two copies of each chromosome, as is typical for normal cells, the cancer cells had anywhere from one to as many as five or six copies; and sometimes there were parts of chromosomes ...
