Answer Key / Explanation : (2) -

In the given base sequence with repeating sequence of UG nucleotide bases, a tetrapeptide is produced with alternating sequence of cysteine and valine. So, it proves that UGU codes for cysteine and GUG codes for valine amino acid and a tetrapeptide with cysteine and valine as alternating amino acids is produced.
