Assume that the DNA of a certain bacteriophage contains 2 x 105 base pairs. How many genes does this number of base pairs correspond to? (The average protein is about 40,000 daltons)© BrainMass Inc. brainmass.com December 24, 2021, 4:46 pm ad1c9bdddf
First, you need to know that the molecular masses of amino acids may vary, but they average 100 daltons. That means that the average protein contains 40,000/100=400 amino acids. Since each amino acid is encoded by three base pairs of DNA (three nucleotides), the protein ...
The expert assumes that the DNA of a certain bacteriophage contains base pairs. How many genes which this number of base pairs corresponds to is determined.
