Gene markers
Gene markers: Detectable genetic traits or distinctive segments of DNA that serve as landmarks for a target gene. Markers are on the same chromosome as the target gene. They must be near enough to the target gene to be genetically linked to it: to be inherited usually together with that gene, and so serve as signposts to it.

Gene pool: The sum total of genes, with all their variations, possessed by a particular species at a particular time.
- Gene product
Gene product: The RNA or protein that results from the expression of a gene. The amount of gene product is a measure of the degree of gene activity.
- Gene silencing
Gene silencing: A mechanism by which cells shut down large sections of chromosomal DNA. Gene silencing is done by incorporating the DNA to be silenced into a form of DNA called heterochromatin that is already silent. The process of gene silencing is important for the differentiation of many different types of cells.
- Gene testing
Gene testing: The testing of a sample of blood (or another fluid or tissue) for evidence of a gene. The aim of gene testing is usually to learn whether a gene for a disease is present or absent.
- Gene transfer
Gene transfer: The insertion of unrelated genetic information in the form of DNA into cells. There are different reasons to do gene transfer. Perhaps foremost among these reasons is the treatment of diseases using gene transfer to supply patients with therapeutic genes. There are also different ways to transfer genes. Some of these methods involve […]
