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

the DNA that makes up the cell's chromosomes can be tightly compacted into a structure that is visible under a microscope, or it can be more loosely distributed and resemble a pile of string.

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 ...

Without centromeres, cells cannot divide properly and the ... thereby contributing to the higher-order structure of the chromosome. Figure 3 shows one model of how CENP-A and CENP-B might interact ...

These cells and others in the body are exact ... The dark bands indicate areas where the structure of the chromosome is dense. Each of the 23 chromosome types has a unique banding pattern.

The improper segregation of chromosomes during cell division leads to abnormalities ... such as the organization of chromatin ...

About 100 cells divide every second in our body. A key protein in cell division is a protein kinase termed Plk1, because it activates other proteins involved in this process. Plk1 is also ...

Females carry two X chromosomes. One of them is ensconced in a corner in the cell called the Barr body, where it can't express many genes, and scientists thought it didn't do much of anything.

Artificial chromosomes are essentially miniature versions of real chromosomes that can replicate alongside their natural counterparts in host cells. They have the potential to be “incredibly useful ...
