G
Gag, Decreased Reflex
Posted on July 24, 2011 |
An abnormal response to a stimulus applied to the sensory components of the nervous system. This may take the form of increased, decreased, or absent reflexes.

G2 Phase
Posted on July 24, 2011 |
Phase of the cell cycle following DNA synthesis and preceding mitosis. The chromosomes are tetraploid in this phase.
G1 Phase
Posted on July 24, 2011 |
Phase of the cell cycle preceding protein systhesis. The subphases of G1 include competence, entry (G1a), progression (G1b), and assembly (G1c), based on the effects of limiting growth factors, nutrients, or inhibitors.
G0 Phase
Posted on July 24, 2011 |
Phase of the cell cycle where cells exist in a quiescent state. These cells have unduplicated DNA, degraded RNA and protein, and low enzyme activity. The ability to switch between G0 and G1 (and vice versa) determines the post-embryonic cell proliferation rate and is defectively controlled in neoplastic cells.
G Phases
Posted on July 24, 2011 |
The interval between two successive cell divisions during which the chromosomes are not individually distinguishable and DNA replication occurs.

GABA-A Receptor
Posted on July 24, 2011 |
Cell surface proteins which bind GAMMA-AMINOBUTYRIC ACID and control an integral membrane chloride channel. GABA-A receptors are the most prevalent inhibitory neurotransmitter receptors in the brain. Several isoforms have been cloned, and they belong to a superfamily which includes nicotinic receptors, glycine receptors, and 5HT-3 receptors. Most GABA-A receptors have separate modulatory sites sensitive to benzodiazepines and to barbiturates.
Gene Expression, Fungal Regulation
Posted on July 24, 2011 |
Any of the processes by which nuclear, cytoplasmic, or intercellular factors influence the differential control of gene action in fungi.
Gene Expression, Enzymologic Regulation
Posted on July 24, 2011 |
Any of the processes by which nuclear, cytoplasmic, or intercellular factors influence the differential control of gene action in enzyme synthesis.
