Four nitrogenous bases and three nucleotides together … WebConsequently, you need to know how many amino acids are in the protein to calculate the length of the mRNA transcript. The protein in the example has a total of 600 amino acids. This implies that 1800 nucleotides, or 600 codons, would be needed. The mRNA transcript also includes a start codon (ATG) and a stop codon (TAA).
