Somatic Cells
A somatic cell is any cell of the body except sperm and egg cells. Somatic cells are diploid, meaning that they contain two sets of chromosomes, one inherited from each parent.
Somatic cells: Any cell in the body except sex cells.
Template: a single DNA strand that serves as pattern for building a new second strand.
Thymine (T): A base; one of the molecular components of DNA and RNA. Always bonds with adenine (T-A).
Somatic cells: Cells of body tissues other than the germline.
Splicing: See gene splicing.
StarLinkTM: An insect-resistant variety of corn that was approved for animal feed only, not labeled for human consumption.
Somatic cells: Any cell in the body except gametes and their precursors.

Most somatic cells of the body cease to express telomerase. However, cells genetically manipulated to express telomerase long after they should have stopped, avoid replicative senescence. Germ cells and some stem cells continue to express the enzyme.

Barr body -- the condensed single X-chromosome seen in the nuclei of somatic cells of female mammals. base pair a pair of hydrogen-bonded nitrogenous bases (one purine and one pyrimidine) that join the component strands of the DNA double helix.
When exposed to infected/dysfunctional somatic cells, TC cells release the cytotoxins perforin and granulysin.
This applies not only to the somatic cells but to the primitive ova and their descendants. For the purpose of illustrating the process of maturation a species may be taken in which the number of nuclear chromosomes is four (Fig. 5).

In theory it is possible to transform either somatic cells (most cells of the body) or cells of the germline (such as stem cells, sperm and eggs).

Somatic cells such as fibroblasts, ovarian cells, muscle cells, and mammary epithelia are grown in cell culture and by genetically modified fusion with the enucleated egg. Commonly, DNA is transferred to the cells using viruses.
polytene chromosomes Chromosomes in the somatic cells of some insects in which the chromatin replicates repeatedly without undergoing mitosis.
polyunsaturated fat A fat having several to many double bonds between carbon atoms.
Telomerase is usually found in cells involved in the production of gametes. It is not normally found in somatic cells.
Cyclin-Dependent Kinases
Some cells stop dividing in G1; others stop in G2.
[Gr. meiosis - reduction]. Two consecutive nuclear divisions whereby the resultant daughter nuclei contain half the chromosome complement of other somatic cells; occurs at time of gametogenesis. Synonym: reduction division.
Somatic cell genetics The study of genes using hybrids (fusions) between the somatic cells of different species.
