Answer 1

Ans-1- the 3 stop codon are UAA, UAG, UGA which are found at the end of mRNA and terminate the synthesis of protein.

Option A is correct.

Ans-2- anticodon ACC encodes for the amino acid tryptophan (trp).

Ans-3- a tRNA with ACC anticodon will make hydrogen bond with UGG codon.

Ans-5- amino acids are linked by peptide bond which is formed by condensation reaction between 2 amino acids.

Peptide bond is correct answer.
