gc含量 meaning in English
gc content
gc-content
Examples
- Dna sequence analysis indicated that tn5gusa5 is prone to insert into low gc content regions ; guanine is a preferential base at the first place and cytosine at the last site of target sequence
在质粒上tn5gusa5也倾向于插入低gc含量区；碱基g和c分别在靶序列的首位和末尾出现的几率高。 - The sequences of 5 . 8s rdna have no differences and they are all 164bp in size . the its - 1 and its - 2 of various species differ from each other in in size , sequence and g + c content , which is necessary for phylogenetic analyses
5 . 85 : dna序列无差异，长度为164bp ，不同物种的its一1和工ts一2在长度、序列及gc含量上均有差异，有利于系统学分析。 - 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。 - Some tendency of tn5gusa5 transposition were found that all preferred sites of tn5gusa5 in xcc 8004 genomic dna are in at - rich regions ; target sequences of tn5gusa5 have some features that the probabilities of guanine and cytosine are high respectively at the head and tail base of target sequence ; the level of gene transcription does not influence insertion density of tn5gusa5 significantly
结果表明， tn5gusa5插入位点有一定的规律性： tn5gusa5在xcc8004基因组上倾向于插入低gc含量( 50左右的区域插入密度最高)区段；插入位点的靶序列有一定的特异性，在靶序列的首位鸟嘌呤出现的几率高，而在靶序列的末位胞嘧啶出现几率高； tn5gusa5的插入密度与该区段基因的转录水平无明显关系。 - Fachb440 was higher than that in the others . alignment based on deduced amino acid sequences indicated that spirulina fachb440 was different from that in other three samples of arthrospira . nucleotide sequence similarity among the three strains of the genus of arthrospira ( 96 . 5 - 99 . 6 % ) was higher than that between arthrospira and spirulina ( 78 . 1 - 78 . 5 % )
Maximaouqdsm ）采螺旋藻（ spirulinafachb440 ） rubisco大亚基基因（ rbcl ）部分片段并进行了序列测定与分析，结果表明：螺旋藻（ spirulinafachb440 ）的gc含量比其他的节旋藻品系高；氨基酸序列分析发现螺旋藻与其他节旋藻品系的差异较大；螺旋藻与节旋藻核着酸序列相似性约为78
