A restriction enzyme cuts a 23,500 bp segment of DNA into three fragments.Fragment A is 7,800 bp, and fragment B is 10,600 bp.How long is fragment C, and which of the fragments will move the farthest in an electrophoresis gel?

Question

Quizplus · Accepted Answer

The length of fragment C can be calculated by subtracting the lengths of fragments A and B from the total length of the DNA segment: 23,500 bp - 7,800 bp - 10,600 bp = 5,100 bp. In electrophoresis, smaller fragments move farther than larger ones, so fragment C, being the smallest, will move the farthest.
