chromatin
英 ['krəʊmətɪn]
美['kromətɪn]
- n. 核染色质；核染质
英英释意
- 1. the readily stainable substance of a cell nucleus consisting of DNA and RNA and various proteins; during mitotic division the chromatin condenses into chromosomes
英文词源
- chromatin (n.)
- protoplasm in cell nuclei, 1882, from German, coined 1879 by German anatomist Walther Flemming (1843-1905), from Latinized form of Greek khromat-, the correct combinational form of khroma "color" (see chroma) + chemical suffix -in (2). Related: Chromatid. Compare chromosome.
