4. You have to compile a restriction map for a linear DNA fragment 8 kb in size. The fragment is labelled with 32P at the 5' ends, allowing you to identify terminal fragments (*). It is then digested with EcoRI, BglI, or a mixture of both enzymes. Following agarose gel electrophoresis, the size of the fragments and the labelled fragments (*) appear as illustrated below. Marker sizes are in kilobases. Two potential restrictions maps for the fragment have been compiled. 3.5 3.0 2.0 1.5 1.0 0.5 1 Department of BGM, Genetics, University of Pretoria EcoRI BglI Mix E E 0.5 kb 1.0 kb 1. 1.0 kb E 1.5 kb 3.0 kb 2.0 kb B B 0.5 B kb B 3.5 kb 3.0 kb E E E 0.5 kb 1.0 kb 2. 3.0 kb 3.0 kb 0.5 B kb B 3.5 kb 2.0 kb 1.5 kb 1.0 kb B B a) If EcoRI has three recognition sites on the DNA molecule (results in four fragments) and BglI has four sites (five fragments), explain how double digestion can result in only 4 bands on the gel. [2] b) Which of the two restriction maps is consistent with the gel results? [1]
