Complete the following problems. Restriction enzymes (REs), which cut D NA at specific sequences, are classic tools in molecular biology. Because of their specificity in cutting DNA, REs can be used to "map" DNA sequences by analyzing the fragments generated upon restriction digest, as in the example shown in Figure 1. Your task is to study the circular plasmid, pMBBS, through restriction digests. You subjected the PMBBS plasmid to complete digestion by different combinations of three REs (EcoRI, BamHI, and Xhol), and analyzed the results on an agarose gel, shown below. Using the data you can glean from this gel, answer the questions that follow. EcoRI BamHI Xhol *The same total amount of DNA was loaded in each lane. 1. What is the total size of the PMBBS plasmid in bp? Answer: bp DNA size ladder 2. How many cut sites on the PMBBS plasmid does each RE have? EcoRI: BamHI: Xhol: Number of fragments: Sizes: 3000 bp 2500 bp 2000 bp 1500 bp 1200 bp 1000 bp 900 bp 800 bp 700 bp 600 bp 500 bp 400 bp 300 bp 200 bp 100 bp VC 100bp Plus DNA ladder from Vivantis Technologies 3. If the PMBBS plasmid were digested with all three REs together, how many fragments would be observed, and what would be the sizes (in bp) of these fragments?

Using the data you can glean from this gel, answer the questions that follow. EcoRI BamHI Xhol *The same total amount of DNA was loaded in each lane. 1. What is the total size of the pMBBS plasmid in bp? Answer: bp + DNA size ladder 2. How many cut sites on the PMBBS plasmid does each RE have? EcoRI: BamHI: Xhol: 3000 bp 2500 bp -2000 bp -1500 bp 1200 bp 1000 bp 900 bp 800 bp 700 bp 600 bp 500 bp 400 bp 300 bp 200 bp 100 bp VC 100bp Plus DNA ladder from Vivantis Technologies 3.
