Industry:Biology
The basic unit of any living organism that carries on the biochemical processes of life. See also: genome, nucleus.
Industry:Biology
A chemical found in the nucleus and cytoplasm of cells; it plays an important role in protein synthesis and other chemical activities of the cell. The structure of RNA is similar to that of DNA. There are several classes of RNA molecules, including messenger RNA, transfer RNA, ribosomal RNA, and other small RNAs, each serving a different purpose..
Industry:Biology
Small cellular components composed of specialized ribosomal RNA and protein; site of protein synthesis. See also: RNA.
Industry:Biology
The self-replicating genetic structure of cells containing the cellular DNA that bears in its nucleotide sequence the linear array of genes. In prokaryotes, chromosomal DNA is circular, and the entire genome is carried on one chromosome. Eukaryotic genomes consist of a number of chromosomes whose DNA is associated with different kinds of proteins..
Industry:Biology
An exact copy made of biological material such as a DNA segment (e.g., a gene or other region), a whole cell, or a complete organism..

See: gene mapping, linkage map, physical map.
Industry:Biology
Using specialized DNA technology to produce multiple, exact copies of a single gene or other segment of DNA to obtain enough material for further study. This process, used by researchers in the Human Genome Project, is referred to as cloning DNA. The resulting cloned (copied) collections of DNA molecules are called clone libraries. A second type of cloning exploits the natural process of cell division to make many copies of an entire cell. The genetic makeup of these cloned cells, called a cell line, is identical to the original cell. A third type of cloning produces complete, genetically identical animals such as the famous Scottish sheep, Dolly. See also: cloning vector.
