Industry:Biology
Diseases in which abnormal cells divide and grow unchecked. Cancer can spread from its original site to other parts of the body and can be fatal.
See also: hereditary cancer, sporadic cancer.
Industry:Biology
Something which causes cancer to occur by causing changes in a cell's DNA.
See also: mutagene.
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
A chromosomal segment that branches off from the rest of the chromosome but is still connected by a thin filament or stalk..
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..
