unineme, a. Cytology.|ˈjuːnɪniːm|
[f. uni- 1 + Gr. νῆµα thread.]
Of a chromatid: having (as usual) just one duplex of DNA.
1963Proc. Nat. Acad. Sci. XLIX. 794 Autoradiographic experiments..have yielded results conformable to a polyneme rather than a unineme structure of the chromosome. 1972Proc. R. Soc. B. CLXXXI. 21 Most cytologists refused (and some still refuse) to accept the simplest and most direct deduction from Taylor's classical labelling experiment, namely that a chromatid, prior to replication, is unineme. 1981Chromosoma LXXXII. 1 The unineme concept is supported by genetical data.
Hence uniˈnemic a., in the same sense; ˈuninemy, the state of having one duplex of DNA per chromatid.
1970Cold Spring Harbor Symp. Quantitative Biol. XXXV. 533/1 The current usage of the hybrid word uninemic is, etymologically, quite incorrect. 1972Proc. R. Soc. B. CLXXXI. 26 Another line of evidence for ‘uninemy’..was provided a few years ago by Miller. 1980Tsitologiya XXII. 83 Chromosomes are uninemic, i.e. each chromonema consists of a single DNA molecule (or a single chain of linked DNA molecules) whose ends are located in telomeres. 1981Chromosome LXXXII. 1 (heading) Evidence for the uninemy of eukaryotic chromatids. |
