Question
Explain why it was suggested that codon is a sequence of three consecutive nucleotides on $\text{m-RNA.}$
✓
Answer
$1.$ If each codon has only one nucleotide, then there will be $4^1 = 4$ codons, which can encode for only four different types of amino acids.
$2.$ If each codon has two nucleotides, then there will be $4^2 = 16$ codons, which can encode for only $16$ different types of amino acids.
$3.$ If each codon has three nucleotides, then there will be $4^3 = 64$ codons, which are sufficient to specify $20$ different types of amino acids.
