The nucleotide sequence of one of the Escherichia coli tyrosine-transfer ribonucleic acids was determined in order to compare its sequence with that of yeast tyrosine-transfer ribonucleic acid. Forty-four positions of both transfer ribonucleic acids are occupied by the same nucleotides if they are arranged in the manner shown here. The information obtained suggests that the conformation of transfer ribonucleic acid molecules may be a greater contributing factor than a specific nucleotide sequence in the interaction of transfer ribonucleic acid with its corresponding aminoacyl-transfer ribonucleic acid synthetase.
测定了一种大肠杆菌酪氨酸转移核糖核酸的核苷酸序列,以便将其序列与酵母酪氨酸转移核糖核酸的序列进行比较。如果按照此处所示的方式排列,两种转移核糖核酸的44个位置由相同的核苷酸占据。所获得的信息表明,在转移核糖核酸与其相应的氨酰基转移核糖核酸合成酶的相互作用中,转移核糖核酸分子的构象可能比特定的核苷酸序列是一个更大的影响因素。
