Question

This diagram shows the process of translation. Which statement is correct?

Answer 1

Answer:

The correct answer would be b.)The mRNA code determines which tRNA molecules are used.

Translation is the process by which polypeptide chain is synthesized in a cell using the codon sequence of mRNA (messenger RNA).

The charged tRNA (transfer RNA which carries amino acid) decodes the codon of mRNA with the help of anti-codon site present in the tRNA.

The anti-codon site of tRNA is complementary to the codon sequence of the mRNA.

The specific tRNA then adds its amino acid to the growing amino acid chain.

The given diagram also shows that the codon sequence (CUA) of mRNA determines that only the tRNA which carries GAU in its anti-codon site can bind to the mRNA.

This specific tRNA then adds its amino acid (leucine) to the growing amino acid chain.

Answer 2

C. The molecule of tRNA bonds with the mRNA, then the tRNA bonds to an amino acid.
