• 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

  • For some of you that haven't I'll just say that it's a protein, it's 238 amino acids, which means that it's about 1,000, actually more than 1,000 atoms in size, and this protein is fluorescent.

    对于那些没听说过的人,我要说它是一蛋白质,它有238个氨基酸,也就意味着它有约1000个,实际上是超过1000个原子,这蛋白质是有萤光的。

  • I'd only have 16 possible two base sequences, that's not enough to specify over 20 amino acids.

    如果两个碱基一组那一共只有十六组合,不够和二十种氨基酸来一一对应

  • One of the amino acids that can be phosphorylated is tyrosine, for example.

    例如,一能够被磷酸化的氨基酸,叫做酪氨酸

  • There are more than 20 amino acids that make up the biological polymers called proteins, so there are 20 choices of each amino acid at a position on a protein.

    而那些称为蛋白质的生物活性多聚体,是由二十不同氨基酸所构成,因此每个蛋白质的,任意位点都有多达二十种氨基酸可供选择

  • That creates a problem in the genetic code in that there's 64 possible sequences but there's only 20 some amino acids, so each amino acid can be specified by more than one codon.

    这里有个问题,遗传密码有六十四可能的序列,而只有二十种氨基酸,因此每种氨基酸都有,不止一密码子与之对应
