| denaturation | Reversible or irreversible loss of function in proteins and nucleic acids resulting from loss of higher order secondary, tertiary or quaternary structure) produced by nonphysiological conditions of pH, temperature, salt or organic solvents. (18 Nov 1997) |
| denaturation temperature of DNA | That temperature at which, under a given set of conditions, double-stranded DNA is changed (50%) to single-stranded DNA; under standard conditions, the base composition of the DNA can be estimated from the denaturation temperature, since the greater the denaturation temperature, the greater the guanine-plus-cytosine content (i.e., GC content) of the DNA. Synonym: melting temperature of DNA. (05 Mar 2000) |
| denature | To induce structural alterations that disrupt the biological activity of a molecule. Often refers to breaking hydrogen bonds between basepairsin double-stranded nucleicacid molecules to produce in single-strandedpolynucleotides or altering the secondary and tertiary structure of a protein, destroying itsactivity. (09 Oct 1997) |
| denatured | 1. Made unnatural or changed from the normal in any of its characteristics; often applied to proteins or nucleic acids heated or otherwise treated to the point where tertiary structural characteristics are altered. 2. Adulterated, as by addition of methanol to ethanol. (05 Mar 2000) |
| denatured alcohol | Ethyl alcohol rendered unfit for consumption as a beverage by the addition of one or several chemicals for commercial purposes (e.g., sucrose octa-acetate). Synonym: industrial methylated spirit, methylated spirit. (05 Mar 2000) |

| dendriform keratitis | <pathology> Inflammation of the cornea (and conjunctiva) due to herpes virus type I, a characteristic finding on physical examination of the eye (cornea) is a dendritic pattern (crystalline or tree-like pattern). (27 Sep 1997) |
| dendrite | A long, branching outgrowth or extension from a neuron, that carries electrical signals from synapses to the cell body, unlike an axon that carries electrical signals away from the cell body. Each nerve cell usually has many dendrites. This classical definition, however, lost some weight with the discovery of axo-axonal and dendro-dendritic synapses. (29 Sep 1997) |
