A section of a genome is cut with three enzymes: A, B, and C. Cutting with A and B yields a 10-kb fragment. Cutting with B and C yields a 2-kb fragment. What is the expected result from a digest with A and C, if the C site lies in between the A and B sites?
A) a 12-kb fragment B) an 8-kb fragment C) an 8-kb and a 2-kb fragment D) a 10-kb and a 2-kb fragment E) a 10-kb, an 8-kb, and a 2-kb fragment
