突变体脱氧核糖核酸误编了一个氨基酸密码。
在所有现有的生命形式中的四个“字母”的遗传密码,即核苷酸,是以三个为单位读取的,每三个核苷酸编码成为一个单独的氨基酸。
In all existing life forms, the four "letters" of the genetic code, called nucleotides, are read in triplets, so that every three nucleotides encode a single amino acid.
并列而排的转移rna阅读邻近的密码子,带来氨基酸并将其以共价键连接起来。
Juxtaposed tRNAs, reading adjacent codes, bring together amino acids, which are then covalently joined to together.
There are 64 combinations of three bases and I only need to describe 20, so there's combinations to spare.
三个一组的碱基产生六十四种组合,而我只需对应二十种氨基酸,所以一种氨基酸会对应不同密码子
There's just more sequences in a three unit codon than I need for the amino acids.
一个氨基酸对应不止一个密码子,由三碱基所构成的密码子
One of them has the right sequence of codons to specify the amino acid sequence of the protein, and the other one has a complimentary sequence.
该段带有正确的密码子序列,能够指导氨基酸序列合成蛋白质,另一段则是它的互补序列
