Solution
The correct option is B 549
The codon is a specific sequence of three consecutive nucleotides that is part of the genetic code and that specifies a particular amino acid in a protein or starts or stops protein synthesis. Codons are 64 in number. Each codon possesses 3 bases. 3 codons are stop codons,. So 61 coding codons are present, each of which can undergo transition and transversion.61(coding codons) × 3² = 549So, the correct answer is '549'.
