Explanation:
Detailed explanation-1: –Three nucleotide bases make up a single codon. Each codon represents a single amino acid. Therefore, nine nucleotide bases are required to code for three amino acids.
Detailed explanation-2: -Answer and Explanation: Three codons are needed to specify three amino acids. Codons can be described as messengers that are located on the messenger RNA (mRNA).
Detailed explanation-3: -We will see that 20 amino acids will be coded by 64 codons. Out of these 64 codons, 61 will code for different amino acids. Rest three are the stop codon or the termination codon (UAA, UAG, UGA). These stop codons are unable to code.
