Cytokinesis: 1. During cell division, the process that partitions the cellular contents including the chromosomes, cytoplasm, and organelles into the two daughter cells. Cytokinesis occurs just after the segregation of the duplicated genome.
2. In a more limited sense, the partition of a cell’s cytoplasm into daughter cells.
See also: Karyokinesis; Mitosis.
Cytology: The medical and scientific study of cells. Cytology refers to a branch of pathology, the medical specialty that deals with making diagnoses of diseases and conditions through the examination of tissue samples from the body. Cytologic examinations may be performed on body fluids (examples are blood, urine, and cerebrospinal fluid) or on material that […]
- Cytomegalovirus (CMV)
A virus that infects 50-85% of adults in the US by age 40 and is also the virus most frequently transmitted to a child before birth. Persons with symptoms have a mononucleosis-like syndrome with prolonged fever and mild hepatitis. Once a person becomes infected, the virus remains alive and usually dormant within that person’s body […]
- Cytometry, flow
Cytometry, flow: Analysis of biological material via detection of the light-absorbing or fluorescing properties of cells, or of subcellular fractions such as chromosomes, as they pass in a narrow stream through a laser beam. Flow cytometry can be used with automated sorting devices to sort successive droplets of a stream into different fractions, depending on […]
- Cytosine (C)
Cytosine (C): One member of the G-C (guanine-cytosine) pair of bases in DNA.
cytosis: 1. Suffix referring to cells, as in anisocytosis (inequality in the size of red blood cells), elliptocytosis (elliptical red cells), and phagocytosis (ingestion of cells). 2. Suffix connoting an increase in cells, as in leukocytosis (increase in white blood cells) and lymphocytosis (increase in lymphocytes).
