1) The molecules inside cells that carry genetic information and pass it from one generation to the next.
2) DNA is the chemical name for the molecule that carries genetic instructions in all living things. The DNA molecule consists of two strands that wind around one another to form a shape known as a double helix. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), and thymine (T). The two strands are held together by bonds between the bases; adenine bonds with thymine, and cytosine bonds with guanine. The sequence of the bases along the backbones serves as instructions for assembling protein and RNA molecules.

Method of identifying gene dosage or expression by measurement of light absorption on an autoradiogram (film) of a band (or spot) representing a DNA, RNA, or protein sample; useful in detecting duplication mutations and heterozygous deletion mutations.
Industry:Medical
1) The normal number of chromosomes in a somatic cell; in humans, 46 chromosomes (22 pairs of autosomes and two sex chromosomes)
2) Diploid is a cell or organism that has paired chromosomes, one from each parent. In humans, cells other than human sex cells, are diploid and have 23 pairs of chromosomes. Human sex cells (egg and sperm cells) contain a single set of chromosomes and are known as haploid.
Industry:Medical
1) A sac or capsule filled with fluid.
2) A closed sac having a distinct membrane and developing abnormally in a body cavity or structure.
3) A body resembling a cyst: as a) a capsule formed about a minute organism going into a resting or spore stage; also: this capsule with its contents b) a resistant cover about a parasite produced by the parasite or the host.
Industry:Medical
1) Location of the heart in the right hemithorax, with the apex directed to the right.
2) An abnormal condition in which the heart is situated on the right side and the great blood vessels of the right and left sides are reversed.
Industry:Medical
1) The condition that results from excessive loss of water from a living organism.
2) State of excessively reduced body water or water deficit.
3) The process of dehydrating; especially: an abnormal depletion of body fluids.
Industry:Medical
1) Twelve pairs of nerves that carry general afferent, visceral afferent, special afferent, somatic efferent, and autonomic efferent fibers.
2) Any of the 12 paired nerves that originate in the brain stem.
3) Any of the 12 paired nerves that arise from the lower surface of the brain with one of each pair on each side and pass through openings in the skull to the periphery of the body.
