|---|---|---|---|
| 설명 | 세포핵 속에 존재하며, 헤마톡실린 등의 염기성 색소로 염색이 되는 물질. 염색사나 염색체의 주성분이다. 세포핵 안에는 호염기성 물질로 DNA와 히스톤(핵단백질)의 복합체를 주성분으로 한다. 원래는 염기성 색소에 쉽게 염색된다는 의미에서 명명되었다. 세포주기에 따라 그 구조가 변한다. 전자현미경으로 전자밀도가 높은 부분은 기능이 낮고 전자밀도가 낮은 부분은 기능적으로 활성도가 높다. 퍼진염색질과 뭉친염색질로 나누기도 한다. 퍼진염색질은 이상 응축을 일으키지 않지만 유전자를 함유하고 있다. 이것에 비해 뭉친염색질은 이상응축을 나타내며, 퇴색반응으로 각 염색체에 특유한 줄무늬를 나타낸다. |

|---|---|
| chromate | A salt of chromic acid. Sodium chromate Cr 51, anionic hexavalent radioactive chromium in the form of sodium chromate (Na251CrO4) with a half-life of 27.8 days; used for the determination of circulating red cell volume and red cell survival time. (05 Mar 2000) |
| chromate reductase | <enzyme> Anaerobic enzyme from cell wall of enterobacter cloacae; ascorbate-reduced phenazine methosulfate can act as electron domor Registry number: EC 1.97.- (26 Jun 1999) |
| chromate stain | <technique> For lead, a method in which tissues preserved in chromate-containing fixatives, such as Regaud's or Orth's fixatives, precipitate lead as yellow lead chromate crystals; formalin-fixed sections are treated with potassium chromate acidified with acetic acid. (05 Mar 2000) |
| chromates | Salts of chromic acid containing the cro(2-)4 radical. (12 Dec 1998) |
| chromatiaceae | Generally strictly anaerobic organisms found in the anaerobic and sulfide-containing parts of all kinds of aquatic environments. (12 Dec 1998) |
| chromatic | Of or pertaining to colour or colours; produced by, or made in, a colour or colours. (05 Mar 2000) |
| chromatic aberration | When using white light through a lens system, it is inevitable that different wave lengths (colours) are brought to a focus at slightly different points. As a consequence, there are chromatic aberations in the image, good microscope objectives are therefore corrected for this at two wave lengths (achromats) or at three wave lengths (apochromats), as well as for spherical aberration. (18 Nov 1997) |
| chromatic apparatus | The deeply staining mass of chromosomes in a dividing cell. (05 Mar 2000) |
| chromatic audition | colour hearing |
| chromatic fibre | The coiled filament in which the genes are located, which extends the entire length of a chromosome and exhibits an intensely positive Feulgen test for DNA. Synonym: chromatic fibre. Origin: chromo-+ G. Nema, thread (05 Mar 2000) |
| chromatic granule | Any readily stainable granule, a granule of chromophil (Nissl) substance. Synonym: chromatic granule. (05 Mar 2000) |
| chromatic spectrum | The continuum of colours that white light forms on passing through a prism or diffraction grating. Synonym: colour spectrum. (05 Mar 2000) |
| chromatic vision | A condition in which objects appear to be abnormally coloured or tinged with colour; designated according to the colour seen: xanthopsia, yellow vision; erythropsia, red vision; chloropsia, green vision; cyanopsia, blue vision. Synonym: chromatic vision, coloured vision, tinted vision. Compare: dyschromatopsia. Origin: chromato-+ G. Opsis, vision (05 Mar 2000) |
| chromatid | Single chromosome containing only one DNA duplex. Two daughter chromatids become visible at mitotic metaphase, though they are present throughout G2. (18 Nov 1997) |
