tRNA
转移核糖核酸；转移RNA
核心释义
an RNA molecule that carries a specific amino acid to the ribosome to add to the protein chain being synthesized
- 1.
转移核糖核酸; 转移RNA
n RNA molecules present in the cell (in at least 20 varieties, each variety capable of combining with a specific amino acid) that attach the correct amino acid to the protein chain that is being synthesized at the ribosome of the cell (according to directions coded in the mRNA)
转移核糖核酸; 转移RNA
用法In use
During protein synthesis, tRNA carries the correct amino acid to the ribosome.
