The genomic DNA of an organism is digested with two restriction enzymes; one of the, PstI (CTGCA/G), while the other., MseI (T/TAA). This would generate the following 3 types of DNA fragments: 

(1) both ends cleaved by PstI (Pst-Pst), 

(2) both ends cleaved by MseI (Mse-Mse), and 

(3) one end generated by each of the two enzymes (Pst-Mse). 

the most frequent fragments in decreasing order,
