g-band造句
- Study on g - banding pattern and spontaneous aberration frequency in an inbred line mouse irm
显带核型和自发畸变率的研究 - G - band , giemsa - band
着丝粒小点带 - We carried out karyotype analysis in patients with autism using g - banding technique
另一个直接的研究方式就是细胞遗传学的检查。 - Bands positively stained after g - banding are commonly negatively stained after r - banding and vice versa
因此, g阳性带通常对应于r阴性带,反之亦然。 - Karyotyping for adanced maternal age was performed by amniocentesis and demonstrated a normal male karyotype ( 46 xy with g - banding )
对此高龄孕妇行羊膜穿刺染色体组型分型检查,先是正常男性( 46xy , g带显带技术) 。 - Methods karyotypes were analyzed by chromosome g - banding in 415 infertile patients with idiopathic azoospermia or severe oligozoospermia
方法运用染色体g显带方法,对415例原发无精症或严重寡精症患者的核型进行分析。 - The trypsin treatment for g - banding is an important factor in obtaining well - banded chromosomes , while the slide aging is not
G显带时胰酶的浓度及处理时间是获得良好显带效果的关键因素,而染色体的片龄似乎并不太重要。 - After g - banding , 65 . 5 % of the chromosome surface is positively stained and the total number of g - banded is 149 . there are 77 positive , 65 negative and 7 variable bands among the 149 g - bands
经g显带技术处理后, 65 . 5的染色体区域呈阳性染色,共显示了149条带,其中阳性带为77 ,阴性带为65 ,可变带为7 。 - 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。 - 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。 - It's difficult to see g-band in a sentence. 用g-band造句挺难的
- In addition , there exists 72 . 2 % of the chromosome surface positively stained with r - banding . 4 . complementarity of g - and r - banding pattern it is generally accepted that chromosome banding patterns appear closely related to differences in dna base composition , and r - bands correspond to gc - rich dna and g - bands to at - rich dna
4 . g 、 r带型的互补性一般认为,染色体的带纹与其碱基组成密切相关, r阳性带对应于gc含量丰富的区域, g阳性带则对应于at含量丰富的区域。
