Gene testing
Gene testing: Testing a sample of blood (or another fluid or
tissue) for evidence of a gene. The evidence can be biochemical, chromosomal, or genetic.
The aim is to learn whether a gene for a disease is present or absent.

Gene therapy
Gene therapy: The treatment of disease by
replacing, altering, or
supplementing a gene that is absent or abnormal and is responsible
for the disease. In
studies of gene therapy for cancer, researchers are trying to bolster
the body's natural

Gene, evolutionarily conserved
Gene, evolutionarily conserved: A gene that has
remained essentially unchanged throughout evolution. Conservation of a gene indicates that
it is unique and essential. There is not an extra copy of that gene with which evolution
can tinker. And changes

Gene, marker
Gene, marker: A detectable genetic
trait or segment of DNA that can be identified and tracked.
A marker gene can serve as a flag for another gene,
sometimes called the target gene. A marker gene must be on
the same chromosome as the target gene a

Gene, zygotic lethal
Gene, zygotic lethal: A gene that is lethal (fatal) for the zygote, the cell formed by the union of a sperm (male sex cell) and an ovum (female sex cell). The zygote would normally develop into an embryo, as instructed by the genetic material within the

covering and substance of the brain (meningoencephalitis) which results in progressive
dementia and general

Genes, breast cancer susceptibility
Genes, breast cancer susceptibility: Inherited factors that predispose
to breast cancer. Put otherwise, these genes make one more susceptible to the disease and
so increase the risk of developing breast cancer. Two of these genes, BRCA1 and BRCA2,

Genetic
Genetic: Having to do with genes, structures found in every cell
of the body. Each gene contains information that directs the activities of cells and
controls the way an individual develops.

Genetic code
Genetic code: The correspondence of the base triplets (trios
composed of A.T.G., or C.) in DNA with the amino acids. The discovery of the genetic code
clearly ranks as one of the premiere events of what has been called the Golden Age of
Biology (and Me

Genetic screening
Genetic screening: Testing a population to identify individuals
at risk for a genetic disease or for transmitting it. Newborns may be screened for PKU
(phenylketonuria), Jews for the gene for Tay-Sachs disease, Blacks for the sickle cell
gene, etc.
