Unformatted text preview: ~30,000 Da Express your answer in kilodaltons: ~30 kDa B. Estimate the number of amino acids in this protein. (30,000 Da / 1) X (1 amino acid / 120 g) = 250 amino acids C. Given this number of amino acids (answer to B), how many nucleotide bases are in the translatable portion of the mRNA transcript for this protein? 250 amino acids X 3 NTB / aa = 750 NTBs D. How many nucleotide bases are in the sense stand of the gene that codes for COP Ia mRNA? a. Fewer than the number of bases in the mRNA. b. The same number of bases as in the mRNA. c. More than the number of bases in the mRNA. Explain the basis for your answer. Sense strand of genic DNA contains non-coding sequences (e.g., regulatory sequences and introns) that are either not transcribed or are spliced out of the final translatable mRNA....
