Pаrt II. Building the recоmbinаnt DNA cоnstruct. Yоu аre ready to follow the major steps required to create a recombinant DNA (your gene of interest inside a vector), from amplification of the gene to verifying that your end product doesn’t have an unexpected mutation. A. For the following three steps, name the key enzyme needed to complete each task. (3 pts) 1. PCR and Gel electrophoresis – Key enzyme:___________ 2. Cleaving DNA - Key enzyme:___________ 3. Ligation into a vector that has the Amp resistance gene – Key enzyme: _____________ The next step will be transformation. For this step, you will use LB Amp plates with X-Gal. B. Assuming your transformation efficiency with the recombinant plasmid was good, but not perfect, how will that plate look? Draw AND explain your result in one sentence. (2 pts) C. Your research mentee, distracted while checking a group chat, forgot to add the recombinant plasmid to the transformation mix. How would his plate look after the transformation attempt? Draw AND explain your result in one sentence. (2 pts) Part III. Verifying the PCR product by gel electrophoresis. You performed a PCR to amplify the open reading frame (from the start codon to the stop codon) of the ParalyzX1 gene, plus an extra 10 bp on each end containing the restriction sites used for cloning. You want to run a gel to check whether the PCR product is the expected size. A. Draw the gel electrophoresis results, assuming the PCR worked perfectly. Include a DNA ladder (with 50 bp, 100 bp, 150 bp, and 200 bp bands), positive control, ParalyzX1 sample, and a negative control. Label each lane accordingly. (4 points). B. Also indicate the expected size of the amplified fragment. (0.5 points)
