|---|---|
| nucleotide deletion | Deletion of a single nucleotide, which in a transcribed gene will lead to a frameshift mutation. Synonym: point deletion. (05 Mar 2000) |
| nucleotide mapping | Two-dimensional separation and analysis of nucleotides. (12 Dec 1998) |
| nucleotide pair | <molecular biology> Two nitrogenous bases (adenine and thymine or guanine and cytosine) held together by weak bonds. Two strands of DNA are held together in the shape of a double helix by the bonds between base pairs. (09 Oct 1997) |
