| 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. |

| chromatin nucleolus | <cell biology> The central portion of a cells nucleus that typically contains a glob of heterochromatin. Origin: Gr. Soma = body (09 Oct 1997) |
|---|
| cell nucleolus | Within most types of eukaryotic cell nucleus, a distinct region, not delimited by a membrane, in which some species of rrna (RNA, ribosomal) are synthesised and assembled into ribonucleoprotein subunits of ribosomes. In the nucleolus rrna is transcribed from a nucleolar organiser, i.e., a group of tandemly repeated chromosomal genes which encode rrna and which are transcribed by RNA polymerase I. (12 Dec 1998) |
|---|---|
| granular component of nucleolus | Area of nucleolus that appears granular in the electron microscope and contains 15nm diameter particles that are maturing ribosomes. In contrast to the pale staining and fibrillar areas. (18 Nov 1997) |
| nucleolus | <cell biology> A small dense body (sub organelle) within the nucleus of eukaryotic cells, visible by phase contrast and interference microscopy in live cells throughout interphase. Contains RNA and protein and is the site of synthesis of ribosomal RNA. The nucleolus surrounds a region of one or more chromosomes (the nucleolar organiser) in which are repeated copies of the DNA coding for ribosomal RNA. (18 Nov 1997) |
| nucleolus organiser | <molecular biology> Loop of DNA that has multiple copies of rRNA genes. See: nucleolus. (18 Nov 1997) |
| nucleolus organiser region | The chromosome region which is active in nucleolus formation and which functions in the synthesis of ribosomal RNA. (12 Dec 1998) |
| false nucleolus | <cell biology> The central portion of a cells nucleus that typically contains a glob of heterochromatin. Origin: Gr. Soma = body (09 Oct 1997) |
| Barr chromatin body | Condensed chromatin of the inactivated X chromosome in female mammals (Barr body). (18 Nov 1997) |
| chromatin | Stainable material of interphase nucleus consisting of nucleic acid and associated histone protein packed into nucleosomes. Euchromatin is loosely packed and accessible to RNA polymerases, whereas heterochromatin is highly condensed and probably transcriptionally inactive. (18 Nov 1997) |
| chromatin 3'-phosphatase-5'-hydroxy kinase | <enzyme> Hydrolyzes the 3'-phosphate end of a polynucleotide duplex followed by ATP-mediated phosphorylation of the 5'-oh end Registry number: EC 3.1.3.- Synonym: chromatin-phosphatase-hydroxykinase (26 Jun 1999) |
| chromatin body | Barr body, condensed X chromosome in female mammalian cell. (18 Nov 1997) |
| chromatin network | The appearance of basophilic material in the nuclei of many cells after fixation. See: chromatin. (05 Mar 2000) |
| chromatin particles | Fine bluish dots thought to represent remnants of the nucleus, occasionally seen in stained erythrocytes. (05 Mar 2000) |
| heteropyknotic chromatin | <cell biology, genetics> The chromosomal regions that are condensed during interphase and at the time of nuclear division. They show what is considered an abnormal pattern of staining as opposed to euchromatin. Can be subdivided into constitutive regions (present in all cells) and facultative heterochromatin (present in some cells only). The inactive X chromosome of female mammals is an example of facultative heterochromatin. (18 Nov 1997) |
| sex chromatin | Condensed chromatin of the inactivated X chromosome in female mammals (Barr body). (18 Nov 1997) |
| oxyphil chromatin | Chromatin that stains with acid dyes, as in interphase nuclei. Synonym: oxyphil chromatin. (05 Mar 2000) |
