chr: Chromosome
start: Start position in chromosome sequence
end: End position in chromosome sequence
name: Name of cytogenetic band
gieStain: Giemsa stain results. Recognized stain value: gneg,gpos50,gpos75,gpos100,acen,gvar,stalk
G帶: 經(jīng)胰蛋白酶绷蹲、NaOH损姜、檸檬酸鹽或尿素等試劑處理后,再經(jīng)吉姆薩染色(giemsa stain),顯示的深淺交替的橫紋便是G帶。染色體的G帶在普通光學(xué)顯微鏡下即可觀察
可變區(qū)(gvar)
柄環(huán)(stalk) 與核仁形成有關(guān)
著絲粒(acen)
負(fù)染色區(qū)(gneg) GC含量比較高,基因數(shù)量比較多
正染色區(qū)(gpos) 根據(jù)染色深淺區(qū)分,gpos25%/50%/75%/100% 染色區(qū) AT含量比較高 基因數(shù)量少
