Researchers at purdue university used synthetic forms of guanine and cytosine
美國普渡大學的研究人員使用的是合成的鳥嘌呤與胞嘧啶。 -
There are four types of nucleic acid, adenine, cytosine, guanine, and thymine *
有四種類型的核酸? ?腺嘌呤、胞核嘧啶、鳥嘌呤、胸腺嘧啶。 -
The most abundant bases are cytosine, thiamine, and uracil ( pyrimidines ) and adenine and guanine ( purines )
最豐富的堿基是胞嘧啶，胸腺嘧啶，尿嘧啶，腺嘌呤和鳥嘌呤。 -
An adenine on one chain is always matched with a thymine * on the other chain, and a guanine with a cytosine
在一個鏈上一個腺嘌呤分子總是與另一個鏈上的一個胸腺嘧啶相匹配，而一個鳥嘌呤總是與一個胞核嘧啶分子相匹配。 -
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由四種堿基組成腺嘌呤、胞嘧啶、鳥嘌呤、胸腺嘧啶，這些分子以成對的方式組成基因的密碼。 -
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
在核酸中的堿基配對高度專一性的原則決定了腺嘌呤與胸腺嘧啶，或鳥嘌呤與胞嘧啶之間的比值為1 ： 1 。 -
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
在質粒上tn5gusa5也傾向于插入低gc含量區；堿基g和c分別在靶序列的首位和末尾出現的幾率高。 -
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
結果表明， tn5gusa5插入位點有一定的規律性： tn5gusa5在xcc8004基因組上傾向于插入低gc含量（ 50左右的區域插入密度最高）區段；插入位點的靶序列有一定的特異性，在靶序列的首位鳥嘌呤出現的幾率高，而在靶序列的末位胞嘧啶出現幾率高； tn5gusa5的插入密度與該區段基因的轉錄水平無明顯關系。
