| anisogamy | <biology> A condition where the gametes of a species have different sizes. In general, the smaller, more mobile gamete is male and the larger one which is packed with food and other things to give the potential zygote a good start (and is less mobile as a result) is the female. The principle behind anisogamy is a division of the labour necessary for two gametes to unite and successfully develop. (09 Oct 1997) |
| anisognathous | Having jaws of unequal size, the upper being wider than the lower. Origin: aniso-+ G. Gnathos, jaw (05 Mar 2000) |
| anisokaryosis | Variation in size of nuclei, greater than the normal range for a tissue. Origin: aniso-+ G. Karyon, nut (nucleus), + -osis, condition (05 Mar 2000) |

| anisometropia | A difference in the refractive power of the two eyes. (12 Dec 1998) |
| anisometropic | 1. Relating to anisometropia. 2. Having eyes of unequal refractive power. (05 Mar 2000) |
| anisometropic amblyopia | A suppression of central vision due to an unequal refractive error (anisometropia) of at least two diopters. This induces a sufficient difference in image size (aniseikonia) that the two images cannot be fused. In order to avoid confusion, the blurrier image is suppressed. Synonym: refractive amblyopia.

| anisomycin | <chemical> An antibiotic isolated from various streptomyces species. It interferes with protein and DNA synthesis by inhibiting peptidyltransferase or the 80s ribosome system. Pharmacological action: antibiotics, antiprotozoal agents, nucleic acid synthesis inhibitors, protein synthesis inhibitor. Chemical name: 3,4-Pyrrolidinediol, 2-((4-methoxyphenyl)methyl)-, 3-acetate, (2R-(2alpha,3alpha,4beta))- (12 Dec 1998) |
