| nucleic acid synthesis inhibitors | Compounds that inhibit cell production of DNA or RNA. (12 Dec 1998) |
|---|---|
| nucleic acids | Highly complex portions of nucleoproteins that yield a mixture of purines and pyrimidines, a ribose or deoxyribose component, and phosphoric acid on complete hydrolysis. The two general types are ribonucleic acid (RNA) and deoxyribonucleic acid (DNA). (12 Dec 1998) |
| nucleic acids, nucleotides, and nucleosides | Complex compounds of high molecular weight occurring in living cells. These are basically of two types, ribonucleic (RNA) and deoxyribonucleic (DNA) acids, both of which consist of nucleotides (nucleoside phosphates linked together by phosphate bridges). (12 Dec 1998) |
| nucleiform | Shaped like or having the appearance of a nucleus. Synonym: nucleoid. (05 Mar 2000) |
| nuclein | The term used by Friedrich Miescher to describe the nuclear material he discovered in 1869, which today is known as DNA. (09 Oct 1997) |
| nucleinase | An obsolete term for nuclease. (05 Mar 2000) |
| nucleinic base | An obsolete term for purine. (05 Mar 2000) |

| nucleobranchiata | <zoology> See Heteropoda. Origin: NL. See Nucleus, and Branchia. Source: Websters Dictionary (01 Mar 1998) |
| nucleocapsid | <virology> The coat (capsid) of a virus plus the enclosed nucleic acid genome. (18 Nov 1997) |
| nucleocapsid proteins | Viral proteins found in either the nucleocapsid or the viral core (viral core proteins). (12 Dec 1998) |
| nucleochylema | Synonym: karyolymph. Origin: nucleo-+ G. Chylos, juice (05 Mar 2000) |
| nucleochyme | The presumably fluid substance or gel of the nucleus in which stainable elements were believed to be suspended; much that was formerly considered to be karyolymph is now known to be euchromatin. Synonym: nuclear hyaloplasm, nuclear sap, nucleochylema, nucleochyme. Origin: karyo-+ L. Lympha, clear water (05 Mar 2000) |
| nucleocortical fibres | General term for projections from a nucleus to an overlying cortical structure; specifically used to designate axons of cerebellar nuclear cells that project to the cerebellar cortex (cerebellar nucleocortical fibres) where they end as mossy fibres. (05 Mar 2000) |
