名词 codon:
a specific sequence of three adjacent nucleotides on a strand of DNA or RNA that specifies the genetic code information for synthesizing a particular amino acidThe open reading frame consists of a series of tri-nucleotidecodonswhich are translated into specific amino acids in the lengthening polypeptide.由一系列三核苷酸密码子组成，多肽延伸时翻译成特定氨基酸。
