Answer: The correct answer is- 3)CCAUGG.
The genetic code can be described as set of instructions that are present in RNA or DNA in the form of nucleotide sequences (having codons, a sequence of three nucleotide depicting particular amino acid).
The nucleotides that are present in RNA are- Adenine (A), Uracil( U), Cytosine( C), and Guanine (G).
Thymine, T (which is present in DNA) is absent in RNA. Instead of Thymine, Uracil (U) is present in RNA.
Thus, option 3) is the right answer.
