How does the structure of tRNA relate to its function in translation?

Answer 1

A tRNA molecule is the mediator between the mRNA and amino acids, the building blocks of protein synthesis.

A tRNA molecule has an antisense codon on it that matches up with the sense codon on an mRNA molecule. The antisense codon on the tRNA molecule is complimentary to the codon on the mRNA. tRNAs have different anitsense codons and carry the amino acid coresponding to whatever particular codon to which it matches.

The tRNA moves and holds the amino acid into an enzyme complex at the site of protein synthesis at which point the amino acid detaches from the tRNA and attaches to the growing protein chain.
