中期染色体 meaning in English
metaphase chromosome
Examples
- Physical mapping of 45s rdna on metaphase chromosomes in several plant species
在多种植物中期染色体上的定位 - ( 2 ) the chromosomes of bmn cells showed the typical characteristics of lepidoterati insects . chromosomes of matephase without apparent centromere are short pole - like and pellet - like
( 2 ) bmn细胞的染色体表现为典型的鳞翅目昆虫的染色体：中期染色体短杆状或颗粒状、无明显的着丝粒。 - Cells only the chromatin or chromosomes are heavily stained , the other components are bleached . after the chromosomes are stained by nama - ur , we have observed that the highest order structure of chromosomes is helical ; while the secondary structure is radically folding . the dna fibres with a diameter of 2530 nm have radically folded into chromatid fibres in a diameter of approximately 250 nm
染色体经dna特异染色后，观察到其最高层次结构是螺旋的，而次级结构存在着放射环结构，即由直径为2530 nm的dna纤丝放射状折叠排列成约250 nm左右的染色单体丝染色单体丝进一步螺旋形成中期染色体结构。 - G - banding the gtg banding ( g - banding ) was carried out by the standard trypsin method with slight modification , which works well for protochordate because a good number of reproducible g - bands are consistently obtained from the embryonic cells of late blastulae and early gastrulae of amphioxus b . belcheri tsingtauense
G带型用稍作修改的标准的胰酶显带技术，进行gtg带纹的显示，它们能较好地显示头索动物青岛文昌鱼的晚期囊胚和早期原肠胚的中期染色体的g带，并且重复性好。 - ( 3 ) the chromosomes obtained by air - drying and chromosomes from the silkworm genital gland are similar in shape . but the numbers and the length of the chromosomes are obviously different . the chromosomes obtained from the genital gland have little difference in length , while the chromosomes of bmn cell are different in length very much
但是，在染色体的数目上有显著的差异。另外，染色体间的长短差别也非常明显。由家蚕生殖腺得到的减数分裂中期染色体和胚胎得到有丝分裂的中期染色体，其染色体长短差异不明显，而binn细胞的中期染色体长短非常不一致，差异非常显著。
