| uneven crossing-over | Unequal crossing-over, crossing-over that happens when the breaks do not occur at precisely homologous points in two chromatid strands, and hence results in localised duplication of genetic material in one chromatid and complementary deletion in the other. (05 Mar 2000) |

| cell fractionation | <technique> Strictly this should mean the separation of homogeneous sets from a heterogeneous population of cells (by a method such as flow cytometry). The term is more frequently used to mean subcellular fractionation i.e. The separation of different parts of the cell by differential centrifugation, to give nuclear, mitochondrial, microsomal and soluble fractions. (26 Mar 1998) |
| dose fractionation | Adminstration of the total dose of radiation (radiation dosage) in parts, at timed intervals. (12 Dec 1998) |
| fractionation | A term used to describe any method for separating and purifying biological molecules. See: cell fractionation. (18 Nov 1997) |
