STUDIES of human chromosomes have been greatly facilitated by the development of newer technics, particularly peripheral blood leukocyte culture. 1–3 Many abnormalities have been described, most of ...

Researchers have discovered an important part of the mechanism involved in how chromosomes are pulled apart during cell division, so that one complete set goes into each of the new cells. Cell ...

Varying between organisms, the number of chromosomes, the structures of organised and packaged DNA information, are normally a constant amount, thus allowing for the successful reproduction of a ...

Chromosomes are tiny, filamentous structures in the cell nuclei of living beings. They contain genes with genetic information, for example, related to the development or control of diseases. Every ...

Loss of the Y chromosome in aging men is widespread and increasingly linked to serious diseases, challenging assumptions that ...

The Y chromosome is among the smallest in the human body and carries the fewest genes. Researchers are paying renewed attention to its role in cancer—specifically, what happens when it vanishes.

Cell division is an essential process in humans, animals and plants as dying or injured cells are replenished throughout life. Cells divide at least a billion times in the average person, usually ...
