You want to clone a 6,000 bp DNA fragment in E. coli. Which cloning vectors would be appropriate? How will you select transformants?
The temperature at which the primers and target DNA hybridize may be changed to influence the stringency of PCR amplification. What effect will changing the hybridization temperature have on the amplification? Let's say you have a certain yeast gene A and want to check whether it has a human equivalent. How might managing the hybridization's rigor benefit you?

- You’re working in a research lab, and your current task is to clone the gene that codes for tyrosinase from potatoes. You grind up some potato, extracts the DNA from it and digests the DNA with two different restriction enzymes (separately, not together): EcoRI and BamHI. You then obtain the cloning vector, pUC19, and digest it with the same two enzymes. You then run a gel which is shown here. You notice that the cloning vector made nice, tight bands on the gel, but the potato DNA just looks like a smear with no distinct bands. However, this is just what you expected. Explain why there are so many bands. Which enzyme would be the better choice to use for cloning the potato DNA, EcoRI, or BamHI? Explain why? Be specific.arrow_forwardYou are trying to clone a gene. You have successfully isolated it from the genomic DNA of an organism using the Hindlll 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.(2 points Does the cloning reaction succeed as described? If so, what is the product obtained? b.
