| 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. |

| bone remodeling | The continuous turnover of bone matrix and mineral that involves first, an increase in resorption (osteoclastic activity) and later, reactive bone formation (osteoblastic activity). The process of bone remodeling takes place in the adult skeleton at discrete foci. The process ensures the mechanical integrity of the skeleton throughout life and plays an important role in calcium homeostasis. An imbalance in the regulation of bone remodeling's two contrasting events, bone resorption and bone formation, results in many of the metabolic bone diseases, such as osteoporosis. (12 Dec 1998) |

| remodeling | A cyclical process by which bone maintains a dynamic steady state through sequential resorption and formation of a small amount of bone at the same site; unlike the process of modeling, the size and shape of remodeled bone remain unchanged. (05 Mar 2000) |
| 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 nucleolus | <cell biology> The central portion of a cells nucleus that typically contains a glob of heterochromatin. Origin: Gr. Soma = body (09 Oct 1997) |
| 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) |
| y chromatin | Brilliantly fluorescent body seen in cells stained with the dye quinacrine which lights up the y chromosomes most brightly. (12 Dec 1998) |
