  Gene



Gene

    1. A unit of DNA that carries information for the biosynthesis of a specific product in the cell. 2. Ultimate unit by which inheritable characteristics are transmitted to succeeding generations in all living organisms. Genes are contained by, and arranged along the length of, the chromosome. The gene is composed of deoxyribonucleic acid (DNA). Each chromosome of each species has a definite number and arrangement of genes, which govern both the structure and metabolic functions of the cells and thus of the entire organism.

The cell consists primarily of an outer plasma membrane, which separates it from the environment; the genetic material (DNA), which encodes heritable information for the maintainance of life; and the cytoplasm, a heterogeneous assemblage of ions, molecules, and fluid.

Generations

Genes

Golgi apparatus
A cytoplasmic organelle which is composed of flattened sacs resembling smooth endoplasmic reticulum. The sacs are often cup-shaped and located near the nucleus, the open side of the cup generally facing toward the cell surface. The function of the Golgi apparatus is to accept vesicles from the endoplasmic reticulum, to modify the contents, and to distribute the products to other parts of the cell or to the cellular environment.

Gamete


Gynandromorph
An individual that is a mosaic of male and female structures. The underlying cause is frequently sex chromosome mosaicism, such that some cells are chromosomal females while others are chromosomal males. Mosaic individuals having simultaneous aspects of both the male and the female phenotype.

Genotype
Genotype is the genetic makeup of an individual organism.

Gene

Guanine
(guanine triphosphate) One of the 4 types of nucleotides that make up DNA. Base pairs with cytosine by 3 hydrogen bonds.

Glucagon
The hormone from the pancreas that causes the release of stored carbohydrate in the liver to restore blood glucose levels. Glucagon uses the second messenger cyclic AMP to exert its biological action.

Glucose
The only simple carbohydrate that circulates in the bloodstream. Glucose is the primary fuel used by the brain. It can also be stored in the liver and muscles in a polymer form known as glycogen.

Glucose Tolerance
The ability of muscle cells and the liver to remove glucose from the bloodstream. As you age, glucose tolerance decreases.
