碱基

• This binding capability can be pinpointed to a characteristic base sequence known as a homeobox
  这种能力与被称为同源框的特定碱基序列有关。
• How these bases are organized along the ladder provides the information stored in genes
  这些碱基沿着阶梯排列的方法为人们提供储存在基因里的信息。
• The base pair ratio , at : gc , is constant within a species but differs between species
  At : gc之间的碱基比具有种内特异性，但在不同种之间往往是不同的。
• 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。
• Base pairing the bonding relationship between purine and pyrimidine bases in the nucleotides of dna and rna
  碱基配对：在dna和rna的核苷酸中，嘌呤和嘧啶之间相匹配的关系。
• Using 3 ' race the transcription stop site mapped 27nt downstream of the putative translation stop codon
  3 ’ race分析结果表明转录的终止位点在翻译终止密码子下游的27个碱基处。
• See gu and li 1996 ) . if homogeneity or stationarity holds , base compositions should remain similar among sequences
  如果同质性或静止性成立，则在序列中的碱基组成应是相似的。
• The products of snupe for 2 y - snp loci were qualified and quantified with the ion - pair reversed - phase hplc
  应用建立的hplc方法检测单碱基引物延伸反应的产物，并且对产物进行了定量。
• Each " rung " is made up of two bases , paired according to the rule that jumped out at watson from his desktop
  每个“横档”由两个碱基组成，它们搭配的原则是华生在书桌旁突然想到的。
• The fact results in the conclusion that the bases related to the stop codon tga are strictly constrained to be used
  由此得出结论：终止密码子对蛋白质编码区碱基的使用具有限制作用。
