Solution
The correct option is C 7
The codon consists of the three nucleotide base which codes for a single amino acid. There are 30 nucleotide bases given in the DNA sequence which is an open reading frame that contains the initial start codon and the stop codon at the end. When they are arranged in the groups of 3 nucleotides in a codon, they synthesize 7 amino acids leaving the start and the stop codon. Thus, the correct answer is option D.
