A student is searching for a 590-bp DNA strand from three bacterial species A, B, and C. She ran the AGE shown below. Using the values shown in the succeeding table, determine if one or more of the three bacterial species possess/es the 590-bp DNA strand by plotting the standard curve from the DNA ladder and approximating the MW of the bands observed from each sample.
