During PCR amplification in preparation for DNA sequencing, why were there different colors at the 3’ ends of the fragments produced? (What did these four colors represent?)
In pcr experiment, Does electrophoresis show that only DNA products of the desired size are present? If not, what do you think is the reason?
You Purified plasmid DNA (a 6.0 kb vector) and got the following results...
DNA conc: 200 ng/µL A260/280: 1.97 A260/230: 2.15
How would you to set up a ligation reaction with 50 ng of digested DNA and a 1254 base pair PCR insert present at a concentration of 23 ng/µL. How should you pipet the necessary nucleotide components (vector and PCR insert) to obtain a 1:5 vector to insert molar ratio? Keep in mind limitations of pipets when giving your answer.(e.g. Pipetes won't go below 0.5µL)

- Which restriction enzyme used in your simulated electrophoresis experiment produced DNA with ‘sticky ends’? Which produced blunt ends? Of these two restriction enzymes, which would you choose to use as donor DNA to graft (or splice) onto a recipient strand of DNA, and why?arrow_forwardIf you wanted to create recombinant DNA using this enzyme(3' T A 5'), would you have to cut both samples of DNA with this enzyme, or could you use two different restriction enzymes? Explain.arrow_forwardIf you were doing a cloning experiment where a plasmid was treated with PstI but the insert DNA did not have a PstI restriction site, what restriction enzyme(s) would be suitable to treat the DNA to be inserted?arrow_forward
- What would spread (fragmented) bands in the electrophoresis gel tell you about the quality of your DNA? Explain briefly, yet clearlyarrow_forwardYou are trying to clone a gene, You have successfully isolated it from the genomic DNA of an organism using the Hindill restriction enzyme. You then take a plasmid with a single EcoRI restriction site and cleave it with EcoRI. You combine these two fragments and treat them with DNA ligase. Answer the two questions below. a. Does the cloning reaction succeed as described? If so, what is the product obtained? b. Explain your answer above,arrow_forwardWhat sequence do the restriction enzymes used in the lab recognize? How do they cut? And how would these different cuts effect cloning? (i.e. compare and contrast how overhang and blunt cuts will differ with cloning.) What organisms were the restriction enzymes used in this lab derived from? Why are restriction enzymes important for the organism that makes them? What is the purpose of multiple cloning sites on pUC19? What size were each of your plasmid fragments?arrow_forward
- As you know, restriction enzymes evolved in different bacterial species independently. The adaptive significance of having a restriction enzyme is that the bacterium has the ability to cut the injected viral DNA into small segments. This destruction of viral DNA prevents the virus from taking over the bacterial cell and killing the cell. What is one benefit of using a restriction enzyme with staggered ends (such as EcoRI) to cut both the DNA insert and the plasmid? Which types of cut sites (staggered with “sticky ends” or blunt ends) are most useful in cloning DNA? Would you expect restriction enzymes in different bacteria genera (Streptococcus, Lactobacter, Escherichia) to have the same recognition sites (DNA sequences). Why or why not?arrow_forwardIf the GAATTC palindrome is repeated four times on the same piece of linear DNA, and the restriction enzyme that recognizes that base sequence is present and digests the DNA, how many DNA fragments will be produced?arrow_forwardWhen making recombinant DNA, why must you use the same restriction enzyme to cut the gene of interest and the plasmid?arrow_forward
- What is the most logical sequence of steps for splicing foreign DNA into a plasmid and inserting the plasmid into bacterium?I) Transform bacteria with recombinant DNA molecule.II) Cut the plasmid DNA using restriction enzymes.III) Extract plasmid DNA from bacterial cells.IV) Hydrogen-bond the plasmid DNA to non-plasmid DNA fragments.V) Use ligase to seal plasmid DNA to non-plasmid DNA A. III, II, IV, V, I B. I, II, IV, III, V C. III, IV, V, I, II D. II, III, V, IV, Iarrow_forwardA. A plasmid is shown with the locations of various restriction enzyme sites labeled. If you cut the plasmid with Xhol and Xbal, which lane of the agarose gel represents the DNA fragments you would expect from the digestion? B. If you now decide to cut the plasmid with EcoRI, how many fragments will be produced and what will their sizes be? C. When running DNA samples on agarose gel, an electric field is applied. Towards which electrode will the DNA migrate and why?arrow_forwardIf I clone a complete eukaryotic gene, including the eukaryotic promoter region, ligate it into a plasmid, and transform it into E. coli, will I be able use the transformed E. coli to make the corresponding protein? Explain why, or why not? If you decide to do this, what would your cloning strategy be?arrow_forward
