生物体内氨基酸与遗传密码关系研究

Study on the relationship between genetic code and amino acids in living body

mRNA的核苷酸序列通过密码子决定了蛋白质的氨基酸序列 ,密码子的使用频率及其在mRNA二级结构中分布的差异 ,影响到氨基酸的相对含量及蛋白质的空间结构。密码子的使用频率及氨酰 -tRNA合成酶对tRNA的识别 。

Tricodons on the messenger RNA nuclectide sequence decide the amino acid sequence of their encoded protein.The differences of the usage rate and the location of tricodon in mRNA secondary structure can affect the relative quantity of amino acid and protein structure,the usage rate of tricodon and the specific recognition of tRNS by aminoacyl tRNA synthetases(aaRS)can affect biological formulae of amino acids in living body.
