11. If pB253 were cleaved with BamHI and Sacl, what are the sizes of the two...
If the target DNA (the 3.266 Kb E. coli genomic Bam HI fragment) has the same restriction sites on each end, there are two possible orientations for the target DNA to insert into the plasmid. The following restriction enzymes would cut the 3.266 kb Bam HI genomic fragment containing the RecA gene once or twice or not at all. In the tables below, list the expected DNA fragment sizes for the two possible orientations. Round the DNA fragment sizes to...
