Chapter 20, Problem 10TYU
DRAW IT You are cloning an aardvark gene, using a bacterial plasmid as a vector. The green diagram shows the plasmid, which contains the restriction site for the enzyme used in Figure 20.5. Above the plasmid is a segment of linear aardvark DNA that was synthesized using PCR. Diagram your cloning procedure, and show what would happen to these two molecules during each step. Use one color for the aardvark DNA and its bases and another color for those of the plasmid. Label each step and all 5' and 3' ends.

In biotechnology, gene cloning is a very important technique. A vector is normally
required to perform this process. The vector commonly used to transform a bacterial host
cell is the plasmid. State the three (3) important regions of the plasmid. Elaborate your
answer.
You are studying a new plasmid, and you digest the plasmid with three restriction
enzymes: Eco RI (E), HindlII (H), and Xbal (X).
You digest the plasmid DNA with each of the following combinations of enzymes and
observe the results on an agarose gel. You are provided a partial plasmid map as shown
below to the right.

- After transformation you were asked to grow bacterial cells transformed with plasmid on a plate that had X-gal and ampicillin. X-Gal is often used as in indicator dye, which turns blue when metabolized by B-galactosidase protein and used to test if cloning experiments have worked. [Note look at the vector diagrams carefully] Briefly explain how you would find the bacterial cells that are transformed with the plasmid with the YFG inserted.arrow_forwardYou are studying a new plasmid, and you digest the plasmid with three restriction enzymes: Eco RI (E), HindlII (H), and Xbal (X).

You have determined that the amplicon you want to clone has enzyme restriction sites for HindIII and EcoRI. After investigation you have seen that the pUC18/19 plasmid also have these enzyme restriction sites in its multiple cloning site (MCS on map included). After enzyme digestion your amplicon is 854 bp long. What length will the recombinant plasmid be after you have inserted your amplicon? Show a calculation.arrow_forward
