The single chromosome displayed here and those on the previous screen are shown in their most compacted state -- they're about to divide, along with the cell, through the process of mitosis.

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 ...

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 ...

Why are the human sex chromosomes called “X” and “Y,” while the other 22 chromosomes are identified only by numbers? The answer begins in the late 1800s, when insect gonad cells, whose large ...

Cytogenetics is the study of chromosomal structure, location and function in cells. It includes the study of chromosome number and appearance (karyotyping), the physical location of genes on ...

Accurate chromosome segregation is the basis ... so that the centromere maintains its identity and location through vast ...

Each chromatid is a full length DNA molecule. The stages outlined in the following example show a cell with a diploid chromosome number of four (two sets of two chromosomes) undergoing cell division.

Phenotypic effects of deletions depend on the size and location of deleted ... result in an acentric chromosome that will most likely be lost during cell division. As with duplications, deletions ...
