Indicators
A cancer-specific antigen associated with both tumors and the developing fetus. The main use of this antigen is as a tumor marker, especially with respect to intestinal cancers. Production of the antigen ceases shortly before birth, but may reappear in people who develop certain types of cancer.
Glossary Term
The nonstaining primary constriction of a chromosome which is the point of attachment of the spindle fiber; provides the mechanism of chromosome movement during cell division; the centromere divides the chromosome into two arms, and its position is constant for a specific chromosome: near one end (acrocentric), near the center (metacentric), or between (submetacentric).
Glossary Term
The process by which a person demonstrates specific knowledge, skills, or abilities in the view of a certifying body. Similarly, the process by which a product or process can achieve certification indicating its suitability for a specific purpose.
Glossary Term

Indicators
The most potent androgen, required for sex development. Dihydrotestosterone is synthesized from testosterone in the prostate gland, testes, hair follicles and adrenal glands by 5-alpha reductase. Dihydrotestosterone exerts its action similar to testosterone, which binds to and activates specific nuclear androgen receptors. After translocation into the nucleus, the activated hormone-receptor complex binds to the androgen response elements on the DNA and activates gene expressions that are required for sex development. Dihydrotestosterone is responsible for the formation of male primary sex characteristics and most male secondary sex characteristics during puberty, such as muscular growth, facial and body hair growth, and deepening of the voice.
Tests
