Glossary is usually defined as an alphabetical list of technical terms in some specialized field of knowledge. This knowledge base glossary provides a collection of knowledge base documents that define many technical terms. These terms are arranged alphabetically, but you can quickly jump to a specific term by selecting its first letter from the index of the knowledge base glossary below.

Development of products by a biological process. Production may be carried out by using intact organisms, such as yeasts and bacteria, or by using natural substances (e.g. enzymes) from organisms.

Cancer-causing agent.

The smallest structural unit of living organisms that is able to grow and reproduce independently.

Growth of cells under laboratory conditions.

Cells which grow and replicate continuously outside the living organism.

Threadlike components in the cell that contain DNA and proteins. Genes are carried on the chromosomes.

A group of genes, cells, or organisms derived from a common ancestor. Because there is no combining of genetic material (as in sexual reproduction), the members of the clone are genetically identical to the parent.

Central Nervous System.

DNA synthesized from a messenger RNA rather than from a DNA template. This type of DNA is used for cloning or as a DNA probe for locating specific genes in DNA hybridization studies.

Cytotoxic T Lymphocytes.
