| cap | <abbreviation> Catabolite (gene) activator protein. 1. Any anatomical structure that resembles a cap or cover. 2. A protective covering for an incomplete tooth. 3. Colloquialism for restoration of the coronal part of a natural tooth by means of an artificial crown. 4. The nucleotide structure found at the 5' terminus of many eukaryotic messenger RNAs, consisting of a 7-methylguanosine connected, via its 5'-hydroxyl group, by a triphosphate group to the 5'-hydroxyl group of the first nucleoside encoded by the DNA; usually symbolised as m7G5'ppp5'N, where N is nucleoside number 1 in the transcribed mRNA and is often itself methylated; the cap is added posttranscriptionally.

| root cap | <botany> A mass of parenchymtous cells which covers and protects the growing cells at the end of a root; a pileorhiza. The issue found at the apex of roots, overlying the root apical meristem and protecting it from friction as the root grows through the soil. Secretes a glycoprotein mucilage as a lubricant.
