Question

Which of the following statements is correct about RNA involvement in translation?

A. The adapter molecule of protein synthesis, the tRNA, recognizes the anticodon of the mRNA molecule to direct protein synthesis

B. Aminoacl-tRNA syntheses are responsible for attaching amino acids to the appropriate tRNAs.

C. The nucleolus is responsible for the synthesis of mRNA catalyzed by RNA Polymerase III

D. rRNA does not contribute to the peptidyl transferase activity of the ribosome

Answer 1

Ans) B. Aminoacl-tRNA syntheses are responsible for attaching amino acids to the appropriate tRNAs.

Explaination:

The adapter molecule of protein synthesis, the tRNA, recognizes the codon of the mRNA molecule to direct protein synthesis

Aminoacl-tRNA syntheses are responsible for attaching amino acids to the appropriate tRNAs and charging of tRNA by using energy released from hydrolysis of ATP.

The nucleolus is responsible for the synthesis of rRNA catalyzed by RNA Polymerase III

23 s rRNA is called as peptidyl transferase so r RNA contribute to peptidyl transferase activity of the ribosome.
