Summary
| Description |
English: Ideograms of G-band pattern of human chromosome 21 in three different resolutions (400, 550 and 850 bphs, bands per haploid set). Different resolutions are corresponding to different band patterns observed through mitotic phase (about relation between banding resolution and mitotic phase, see, for example, Fig.3 in W Sethakulvichaia (2012)).
Legend: Black and gray is Giemsa positive. Red is centromere. Light blue is variable region. Dark blue is stalk. At the right, centromere position (center) and q arm terminus position (bottom), counted from p arm terminus (top) in Mbp (mega base pairs), are labeled. Physical length (sometimes referred as "absolute length") is not labeled. Because physical length of chromosomes vary while mitosis. (typical human chromosome physical length is in the order of from several micrometers to ten and several micrometers. See, for example, Category:Human chromosome images with scale bars.).日本語: ギムザ染色時に見られるヒト21番染色体の、400, 550, 850という三つの異なる解像度（bphs, bands per haploid set、ハプロイドセット当たりバンド数）での、バンド図。異なる解像度は、染色体が染色体凝縮の過程で見せる、異なるバンドパターンに相当する（染色体凝縮とバンドパターンの解像度の関係については例えば W Sethakulvichaia (2012) の図３などを参照のこと）。黒および灰色はギムザ染色で染まる部分を、赤色はセントロメアを、淡い青色は変異領域を、濃い青色は付随体柄を、それぞれ表す。
右端には、p腕末端（画像上端）からMbp（メガベースペア、百万塩基対）単位で数えた、セントロメアの位置（画像中央）とq腕末端の位置（画像下端）を示す。染色体の物理的長さ（絶対長さとも言われる）は染色体凝縮の過程で変化するため記されていない（ただしヒト染色体のおよその物理的長さは、数μｍから十数μｍのオーダー。Category:スケールバー付きヒト染色体画像 などを参照のこと）。 バンド図の描画は米国NCBIの Genome Decoration Page による。描画に使用されたデータはゲノム・リファレンス・コンソーシアム2014年発表のヒトゲノム・ビルド38・パッチ2（GRCh38.p2）。バンド図を描くために使用された生データは、下のSource欄のリンクから取得できる。 |
