|---|---|---|---|
| 설명 | 암수의 성을 결정하는 데 중요한 구실을 하는 염색체. 이것에 대하여 보통의 염색체를 보통염색체라고 한다. 암수의 구별이 있는 생물에서는 암수에 따라 다른 형과 수를 나타내는 염색체이며, 보통염색체에 비해 염색성이나 행동에서 차이가 있다. 특히 동물의 성염색체는 그런 경향이 강하다. 휴지기 및 핵분열 전기에 뚜렷한 이상응축을 나타내며 감수분열 때는 다른 염색체보다 먼저 앞서거나 끌려가는 행동을 보여준다. |

| 영문 | chromosome | 한글 | 염색체 |
|---|---|---|---|
| 설명 | 유전정보를 담고 있는 DNA가 모여서 이루는 구조물로 핵속에 위치한다. 세포가 분열할 때 이것을 더욱 뚜렷이 관찰할 수가 있다. 이것은 사람처럼 고등생물체에서 너무나 많은 정보를 담고 있어, 엄청난 길이(사람에 있어서 전 DNA를 길이로 따지면 약 2m가 된다)가 된 DNA를 작은 핵이란 공간속에 보관하기 위해서 만들어진 구조이다. 이 염색체의 수는 생물의 종에 따라 다르며 사람의 경우는 46개이다. |

| 영문 | chromosome abnormality | 한글 | 염색체이상 |
|---|---|---|---|
| 설명 | 염색체의 수나 구조의 이상. 이상이 생긴 세포나 개체는 유전적인 이상을 일으켜 사람의 경우, 다운 증후군-터너 증후군 따위의 여러 가지 형태로 나타난다. |

| gene rearrangement | A structural alteration of a chromosome that causes a change in the orderof its loci. (09 Oct 1997) |
|---|---|
| gene rearrangement, alpha-chain T-cell antigen receptor | Ordered rearrangement of T-cell variable gene regions coding for the alpha-chain of antigen receptors. (12 Dec 1998) |
| gene rearrangement, beta-chain T-cell antigen receptor | Ordered rearrangement of T-cell variable gene regions coding for the beta-chain of antigen receptors. (12 Dec 1998) |
| gene rearrangement, b-lymphocyte | Ordered rearrangement of b-lymphocyte variable gene regions coding for the immunoglobulin chains, thereby contributing to antibody diversity. It occurs during the differentiation of the immature b-lymphocyte. (12 Dec 1998) |
| gene rearrangement, b-lymphocyte, heavy chain | Ordered rearrangement of b-lymphocyte variable gene regions thereby contributing to antibody diversity. It occurs during the first stage of differentiation of the immature b-lymphocyte. (12 Dec 1998) |
| gene rearrangement, b-lymphocyte, light chain | Ordered rearrangement of b-lymphocyte variable gene regions coding for the kappa or lambda light chains, thereby contributing to antibody diversity. It occurs during the second stage of differentiation of the immature b-lymphocyte. (12 Dec 1998) |
| gene rearrangement, delta-chain T-cell antigen receptor | Ordered rearrangement of T-cell variable gene regions coding for the delta-chain of antigen receptors. (12 Dec 1998) |
| gene rearrangement, gamma-chain T-cell antigen receptor | Ordered rearrangement of T-cell variable gene regions coding for the gamma-chain of antigen receptors. (12 Dec 1998) |
| gene rearrangement, t-lymphocyte | Ordered rearrangement of T-cell variable gene regions coding for the antigen receptors. (12 Dec 1998) |
| rearrangement | A restructuring; e.g., in a molecule. Amadori rearrangement, a rearrangement that occurs in cross-linking reactions seen in collagen and in protein glycosylations; e.g., conversion of N-glycosides of aldoses to N-glycosides of the corresponding ketoses. (05 Mar 2000) |
| DNA rearrangement | <molecular biology> Wholesale movement of sequences from one position to another in DNA, such as occur somatically, for example in the generation of antibody diversity. (18 Nov 1997) |
| accessory chromosome | A chromosome existing without its normal homologous chromosome; at the reduction division of gametogenesis an accessory chromosome is likely to be included in one daughter cell and not in the other, but may be lost completely by lagging behind on the equatorial plate. Synonym: monosome, odd chromosome, unpaired allosome, unpaired chromosome. (05 Mar 2000) |
| acentric chromosome | A fragment of a chromosome lacking a centromere and unable to attach to the mitotic spindle, therefore unable to take part in the division of a nucleus and randomly distributed in daughter cells. Synonym: acentric fragment. (05 Mar 2000) |
| acrocentric chromosome | A chromosome with the centromere placed very close to one end so that the short arm is very small, often with a satellite. (05 Mar 2000) |
| balanced chromosome | <genetics> A chromosome which is unable to pair with its homologue and participate in homologus recombination during meiosis because it contains several inversion mutations (that is, has segments which have become flip-flopped). (09 Oct 1997) |
