|---|---|---|---|
| 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. |

| 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. |

| chromosome banding | Staining of bands, or chromosome segments, allowing the precise identification of individual chromosomes or parts of chromosomes. Applications include the determination of chromosome rearrangements in malformation syndromes and cancer, the chemistry of chromosome segments, chromosome changes during evolution, and, in conjunction with cell hybridization studies, chromosome mapping. (12 Dec 1998) |

| Giemsa chromosome banding stain | <technique> A unique chromosome staining technique, used in human cytogenetics to identify individual chromosomes, which produces characteristic bands. It utilises acetic acid fixation, air drying, denaturing chromosomes mildly with proteolytic enzymes, salts, heat, detergents, or urea, and finally Giemsa stain; chromosome bands appear similar to those fluorochromed by Q-banding stain. Synonym: Giemsa chromosome banding stain. (05 Mar 2000) |

| quinacrine chromosome banding stain | q-banding stain |
| banding | <dentistry> The process of cementing orthodontic bands to your teeth. (08 Jan 1998) |
| banding of chromosomes | Treatment of chromosomes to reveal characteristic patterns of horizontal bands. Thanks to these banding patterns that resemble bar codes, each human chromosome is distinctive and can be identified without ambiguity. (12 Dec 1998) |
| banding pattern | <genetics> Chromosomes stained with certain dyes, commonly quinacrine (Q banding) or Giemsa (G banding), show a pattern of transverse bands of light and heavy staining that is characteristic for the individual chromosome. The basis of the differential staining, which is the same in most tissues, is not understood: each band represents 5-10% of the length, about 10exp7 base pairs, although this is not true for polytene chromosomes in Drosophila that show more than 4000 bands. (18 Nov 1997) |
| BrDu-banding | The labeling of chromosomes in proliferating tissue by adding an excess of bromodeoxyuridine, which replaces the uridine incorporated in RNA and fluoresces in ultraviolet light; the bands result from sister chromatid exchanges. (05 Mar 2000) |
| G-banding | <genetics> Chromosomes stained with certain dyes, commonly quinacrine (Q banding) or Giemsa (G banding), show a pattern of transverse bands of light and heavy staining that is characteristic for the individual chromosome. The basis of the differential staining, which is the same in most tissues, is not understood: each band represents 5-10% of the length, about 10exp7 base pairs, although this is not true for polytene chromosomes in Drosophila that show more than 4000 bands.

It utilises acetic acid fixation, air drying, denaturing chromosomes mildly with proteolytic enzymes, salts, heat, detergents, or urea, and finally Giemsa stain; chromosome bands appear similar to those fluorochromed by Q-banding stain. Synonym: Giemsa chromosome banding stain. (05 Mar 2000) |
| R-banding | See: R-banding stain. (05 Mar 2000) |
| R-banding stain | <technique> A reverse Giemsa chromosome banding method that produces bands complementary to G-bands; induced by treatment with high temperature, low pH, or acridine orange staining; often used together with G-banding on human karyotype to determine whether there are deletions. (05 Mar 2000) |
| C banding | <molecular biology> Method of defining chromosome structure by staining with Giemsa and looking at the banding pattern in the heterochromatin of the centromeric regions. Giemsa banding (G banding) of the whole chromosome gives higher resolution. Q banding is done with quinacrine. (18 Nov 1997) |
| C-banding stain | <technique> A selective chromosome banding stain used in human cytogenetics, employing Giemsa stain after most of the DNA is denatured or extracted by treatment with alkali, acid, salt, or heat; only heterochromatic regions close to the centromeres and rich in satellite DNA stain, with the exception of the Y chromosome whose long arm usually stains throughout. Synonym: centromere banding stain. (05 Mar 2000) |
| centromere banding stain | <technique> A selective chromosome banding stain used in human cytogenetics, employing Giemsa stain after most of the DNA is denatured or extracted by treatment with alkali, acid, salt, or heat; only heterochromatic regions close to the centromeres and rich in satellite DNA stain, with the exception of the Y chromosome whose long arm usually stains throughout. Synonym: centromere banding stain. (05 Mar 2000) |
| reverse banding | <technique> A reverse Giemsa chromosome banding method that produces bands complementary to G-bands; induced by treatment with high temperature, low pH, or acridine orange staining; often used together with G-banding on human karyotype to determine whether there are deletions. (05 Mar 2000) |
| prometaphase banding | Banding done in the stage of mitosis intermediate between prophase and metaphase. (05 Mar 2000) |
Synonyms : Bandings, Chromosome, Chromosome Bandings
| chromosome banding |
Staining of chromosomes in such a way that light and dark areas occur along the length of the chromosomes in repeatable patterns. Lateral comparisons identify pairs. Each chromosome can be identified by its banding pattern.
