Autonomous self-replicating extra-chromosomal circular DNA molecule present in bacteria and yeast. Note 1: Plasmids replicate autonomously each time a bacterium divides and are transmitted to the daughter cells. Note 2: DNA segments are commonly cloned using plasmid vectors.
Industry:Biology; Chemistry
Noncommittal term used instead of adsorption or absorption when it is difficult to discriminate experimentally between these two processes.
Industry:Biology; Chemistry
Nonprotein entity essential for an enzyme’s activity and tightly bound to the enzyme molecule in its active form.
Industry:Biology; Chemistry
Note: The higher this value above one, the greater the risk. If the value is below one, there should be no risk as a result of the predicted exposure.
Industry:Biology; Chemistry
Number of instances of existing cases of a given disease or other condition in a given population at a designated time; sometimes used to mean prevalence rate. Note: When used without qualification, refers usually to the situation at a specified time (point prevalence).
Industry:Biology; Chemistry
Numerical constant in a rate-of-reaction (v) equation; for example, v = k (A)a(B)b.......where (A), (B) etc. are reactant concentrations, k is the rate constant, and a, b, etc. are corresponding empirical constants. Note: For further consideration of the relevant mathematics.

Industry:Biology; Chemistry
Numerically specified low risk of exposure to a potentially toxic substance (for example, 1 in 1000) or socially acceptable low risk of adverse effects from such an exposure applied to decision making in regard to chemical safety.
Industry:Biology; Chemistry
Objective evidence of a disease, deformity or an effect induced by an agent, perceptible to an examining physician.
Industry:Biology; Chemistry
Observable structural and functional characteristics of an organism determined by its genotype and modulated by its environment.
