g A linear fragment of DNA is 30kb in length. It was subjected to digestion by Pst1, which resulted in 17, 9, 3, 1 kb fragments. The same DNA fragment is digested with EcoRV to get 12, 9, 5, 4 kb fragments. In a double digest with both enzymes, the following fragments sizes were observed; 8, 7, 5, 4 , 3, 2, 1kb fragments. Determine the order of the restriction sites.
