Autoradiography: A technique using X- ray film to visualize molecules or fragments of molecules that have been radioactively labeled. Autoradiography has many applications in the laboratory. Autoradiography can, for example, be used to analyze the length and number of DNA fragments after they are separated from one another by a method called gel electrophoresis.
Autosomal: Pertaining to a chromosome that is not a sex chromosome. People normally have 22 pairs of autosomes (44 autosomes) in each cell, together with 2 sex chromosomes, X and Y in a male and X and X in a female.
- Autosomal chromosome
Autosomal chromosome: Any chromosome except for the sex chromosomes. Humans have 44 autosomal chromosomes, or autosomes.
- Autosomal dominant
Autosomal dominant: A pattern of inheritance in which an affected individual has one copy of a mutant gene and one normal gene on a pair of autosomal chromosomes. (In contrast, autosomal recessive diseases require that the individual have two copies of the mutant gene.) Individuals with autosomal dominant diseases have a 50-50 chance of passing […]
- Autosomal dominant hereditary spastic paraplegia
Autosomal dominant hereditary spastic paraplegia: A degenerative disorder of nerves with progressive spasticity of the legs. Abbreviated as AD-HSP. Spasticity is a state of increased muscle tone. Paraplegia refers to the legs (quadriplegia refers to both the arms and legs). In hereditary spastic paraplegia there is an insidiously progressive condition characterized by weakness beginning in […]
- Autosomal recessive
Autosomal recessive: A genetic condition that appears only in individuals who have received two copies of an autosomal gene, one copy from each parent. The gene is on an autosome, a nonsex chromosome. The parents are carriers who have only one copy of the gene and do not exhibit the trait because the gene is […]
