Answer: The correct answer is option e.
Step-by-step explanation:
A codon refer to the sequence of three nucleotide in DNA or RNA which is also termed as unit of genetic code.
It is present in both prokaryotic as well as eukaryotic cells.
A codon codes for specific amino acid. It does not catalyze any reaction.
There are 64 universal codons; however, only 20 amino acids. It is the reason that many codons may code for single amino acid.
For example, UUU and UUC code for phenylalanine, AUU, AUC, and AUA code for isoleucine, et cetera.
