| vegetable base | <chemistry, pharmacology> One of a large group of nitrogenous substances found in naturally in plants. They are usually very bitter and although the plant may be poisonous, many have extracts that are pharmacologically active. Examples are atropine, caffeine, coniine, morphine, nicotine, quinine, strychnine. The term is also applied to synthetic substances which have structures similar to plant alkaloids, such as procaine. (29 Sep 1997) |

| cavity preparation base | <dentistry> A layer of dental cement, sometimes medicated, that is placed in the deep portion of a cavity preparation to protect the pulp, reduce the bulk of a metallic restoration, or eliminate undercuts. Synonym: cavity preparation base. (05 Mar 2000) |
| Reid's base line | <anatomy, radiology> A line drawn from the inferior margin of the orbit to the auricular point at the superior border of the orifice of the external auditory meatus and extending backward to the centre of the occipital bone. It is used as the zero plane in computed tomography. (05 Mar 2000) |

| complementary base pairing | <molecular biology> The pairing of complementary nucleotide bases (adenine and thymine, guanine and cytosine) to each other via hydrogen bonds from opposite strands of a double stranded nucleic acid (such as DNA or RNA), thereby holding the double-stranded nucleic acid together. (09 Oct 1997) |
| complementary base pairs | <molecular biology> The crucial property of DNA is that the two strands are complementary: Guanine and cytosine are complementary and pair up through their hydrogen bonds, as are adenine and thymine that only form two hydrogen bonds. (adenine and uracil in RNA). (18 Nov 1997) |
| wobble base | The 3' codon base that is less strictly specified in the genetic code. See: wobble, wobble hypothesis. (05 Mar 2000) |
| base pair |
The basic units of DNA and RNA, base pairs are chemical structures made up of the chemicals adenine, thymine, guanine and cytosine, which are designated by the letters A, T, G and C, respectively. Adenine always pairs with thymine and guanine always pairs with cytosine, creating the pairs or nucleotides in which genetic information is found.

| base pair |
Two nitrogenous bases held together by weak bonds. In a DNA molecule adenine always pairs with thymine while cytosine always pairs with guanine. Thus, one DNA strand directs the synthesis of the other strand. This specificity of DNA base pairing is what enables accurate replication of a DNA molecule.
