Referring to the nucleus of something.

(biochemistry, genetics) Any acidic, chainlike biological macromolecule consisting of multiple repeat units of phosphoric acid, sugar and purine and pyrimidine bases; they are involved in the preservation, replication and expression of hereditary information in every living cell

plural of nucleic acid

Any nucleic acid composed of bases other than adenine, guanine, thymine, uracil and cytosine and/or sugars other than ribose and deoxyribose, that could form the basis of extraterrestrial carbon-based life.

(biochemistry) An analog of RNA in which the sugar component is threose—considered to be a primordial precursor to RNA

(biochemistry) A synthetic nucleic acid; an analogue of DNA in which the sugar backbone is glycerol or a related glycol

(biochemistry, genetics) a synthetic form of RNA, in which the ribose is modified to be locked into a specific conformation by adding extra chemical bonding.

(biochemistry) A synthetic organic polymer similar to DNA or RNA; the sugar backbone of nucleic acids is replaced by N-(2-aminoethyl)-glycine linked through peptide bonds - considered a possible precursor to RNA

plural of deoxyribose nucleic acid

plural of ribose nucleic acid
