Answer #1

3)

Gel Lane Plasmid Restriction Enzyme Number of Bands Observed Estimated Size (bp) of each band
2 (tube 1) A N/A; uncut 4
  • Undeterminate size (2 nicked bands at the top)
  • 9 kb
  • 3.5 kb
3 (tube 2) B N/A; uncut 4
  • Undeterminate size (Nicked bands at the top)
  • 9 kb
  • 3.4 kb
4 (tube 3) A BclI 2
  • 4 kb
  • 1.4 kb
5 (tube 4) B BclI 2
  • 3 kb
  • 2.4 kb
6 (tube 5) A EcoRI 1 3.4 kb
7 (tube 6) B EcoRI 1 3.4 kb

4)

The Uncut lane was expected to have only one band, since only one plasmid is loaded as uncut DNA. However, 4 bands are observed. This discrepancy is due to various conformations of circular DNA. Plasmids are circular DNA molecules and can, therefore, adopt various conformational states. These conformations are relaxed, coiled, supercoiled and nicked.

The Supercoiled form of Plasmid DNA migrates according to the linear size of the DNA molecule, while other coformations migrate at a slower rate, thereby showing up as separate bands on the agarose gel.

    How did you EXPECT your uncut lane to look in the gel image? What ACTUALLY happened? What is a plausible explanation if there was any discrepancy? How did the observed BclI and EcoRI digest results compare to the expected results? If they differed, list a potential reason why? BclI was incubated at 50°C, while EcoRI was incubated at 37°C. Why was this necessary? What might you predict to occur if you accidentally switched the temperatures? 3) Using the DNA ladder,...
