Meiosis, a type of cell division specific to reproduction, avoids this by halving the number of chromosomes in a cell. The cell shown here will divide twice, resulting in four cells. Each of these ...

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 ...

In the United States, more than 11% of men under the age of 49 are infertile. While the causes are varied and range from ...

Chromosomes carry genetic information in a molecule called DNA. A type of cell division called mitosis ensures that when a cell divides each new cell produced has the same genetic information.

The film "Mitosis" explores the process of cell division, specifically focusing on mitosis, which is essential for the growth ...

Reproductive cells—sperm and eggs—contain ... This halving occurs through meiosis, a specialized type of cell division. During meiosis, one progenitor cell duplicates its DNA and goes through ...

Black yeasts, in particular, showed unexpected reproduction methods. One species, Hortaea werneckii, was found to alternate between fission, the division of a parent yeast cell into two identical ...

A genetic mutation in mice affects cells required for sexual reproduction and holds clues about male infertility that could pave the way for new treatments and male contraceptives, a Rutgers ...
