| base pairing | <molecular biology> The specific hydrogen bonding between purines and pyrimidines in double stranded nucleic acids. In DNA the pairs are adenine and thymine and guanine and cytosine, while in RNA they are adenine and uracil and guanine and cytosine. Base pairing leads to the formation of a DNA double helix from two complementary single strands. (15 Nov 1997) |

| base projection | Radiographic projection devised to obtain direct visualization of the base of the skull. Synonym: axial view, base projection, submental vertex projection, submentovertical projection, verticosubmental view. (05 Mar 2000) |
| base sequence | <molecular biology> The order of nucleotide bases in a DNA molecule. (09 Oct 1997) |
| base sequence analysis | <molecular biology> A method, sometimes automated, for determining the base sequence. (09 Oct 1997) |
| base-stacking | A clustering of DNA or RNA bases in which the rings lie on top of each other. (05 Mar 2000) |
| base substitution | <molecular biology> One nucleotide base is replaced by another in a DNA molecule. This is also called a point mutation. (09 Oct 1997) |
| base units | The fundamental unit's of length, mass, time, electric current, thermodynamic temperature, amount of substance, and luminous intensity in the International System of Units (SI); the names and symbols of the unit's for these quantities are meter (m), kilogram (kg), second (s), ampere (A), kelvin (K), mole (mol), and candela (cd). See: International System of Units. (05 Mar 2000) |
| base view | A radiographic projection showing the base of the skull, positions of the mandibular condyles, and zygomatic arches. Synonym: base view, submental vertex radiograph. (05 Mar 2000) |
| Bronsted base | Any molecule or ion that combines with a proton; e.g., OH-, CN-, NH3; this definition replaces the older and more limited concepts of base. (05 Mar 2000) |
| 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) |
| general acid-base catalysis | A catalytic reaction that involves the tranfer of a proton to or from anon-water molecule. (09 Oct 1997) |
| record base | <cell biology> A hypothetical cell adhesion molecule possibly involved in sponge cell adhesion, existence unproven. (18 Nov 1997) |
| mass at base of tongue | <radiology> Lingual thyroid, thyroglossal duct cyst, haemangioma, other neoplasm (12 Dec 1998) |
| 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) |
