例句与用法

1.Researchers at purdue university used synthetic forms of guanine and cytosine

美国普渡大学的研究人员使用的是合成的鸟嘌呤与胞嘧啶。

2.There are four types of nucleic acid , adenine , cytosine , guanine , and thymine *

有四种类型的核酸? ?腺嘌呤、胞核嘧啶、鸟嘌呤、胸腺嘧啶。

3.The most abundant bases are cytosine , thiamine , and uracil ( pyrimidines ) and adenine and guanine ( purines )

最丰富的碱基是胞嘧啶，胸腺嘧啶，尿嘧啶，腺嘌呤和鸟嘌呤。

4.Cytidine ( cytosine nucleoside ) a nucleoside formed when cytosine is linked to dribose via a - glycosidic bond

胞嘧啶核苷：当胞嘧啶通过糖苷键与d核糖接合形成的核苷。

5.An adenine on one chain is always matched with a thymine * on the other chain , and a guanine with a cytosine

在一个链上一个腺嘌呤分子总是与另一个链上的一个胸腺嘧啶相匹配，而一个鸟嘌呤总是与一个胞核嘧啶分子相匹配。

6.Normal dna consists of four bases - adenine , cytosine , guanine and thymine ( known as a , c , g , t ) - molecules that spell out the genetic code in pairs

正常dna由四种碱基组成腺嘌呤、胞嘧啶、鸟嘌呤、胸腺嘧啶，这些分子以成对的方式组成基因的密码。

7.The base ratio of 1 : 1 for the bases adenine and thymine and the bases cytosine and guanine was the first clue to the specificity of base pairing in the nucleic acids

在核酸中的碱基配对高度专一性的原则决定了腺嘌呤与胸腺嘧啶，或鸟嘌呤与胞嘧啶之间的比值为1 ： 1 。

8.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。

9.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。
