r带 meaning in English

r-band

3 . r - banding the rhg banding ( r - banding ) technique used was the method of dutrillaux and lejeune ( 1971 ) slightly modified
R带型青岛文吕鱼染色体的核型及带型研究参照nutrillaux和lejeune ( 1971 )的r带显示方法，稍作修改。
The total number of r - bands found in the chromosomes is 100 , which is approximately 1 / 4 to 1 / 5 of that of the vertebrate metaphase chromosome r - bands . they consist of 57 positive , 33 negative and 10 variable bands
在100条r带中阳性带有57个，阴性带有33个，可变带有10个，约有722 %的染色体区域显示r带阳性结果。
As the number of r - bands is associated with that of genes , and most genes that have been mapped to mammalian chromosomes with sufficient precision are usually distributed in r - bands rather than in g - bands . this is apparently in agreement with the hypothesis of two rounds of extensive gene duplication leading to the origin of the vertebrates
R带的数目与基因的多少相关，许多哺乳动物的基因已精确地进行了染色体定位，大量报道证明它们一般分布在r带上，而不是g带上，文昌鱼r带的数目恰恰与脊椎动物起源时发生了两次基因倍增的假设相吻合。
