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 ...

To make the move from asexual to sexual reproduction ... (Cytokinesis describes the division of the rest of the cell.) Almost all of the DNA duplication in your body is carried out through ...

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 ...

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.

Prokaryotes, which include bacteria and single-celled microorganisms called Archaea, usually pass their chromosomal DNA on to their offspring asexually. In other words, a bacterial cell reproduces ...

The biological factory that produces reproductive cells has a robust quality control system to identify and eliminate eggs ...

D uring meiosis, the cell division process central to sexual reproduction, all chromosomes must figure out where to destroy the protein cohesin—the molecular glue holding chromosomes together ...
