This is a calculation molecular biology problem that enables you to convert daltons (molecular mass) to protein sizes and to the number of genes.
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)
First, you need to know that the molecular masses of amino acids may vary, but they average 100 daltons. That ...
