Where would you expect to find this DNA on a gel? A) DNA would be highly supercoiled and would be found in the band seen in the positive pole (bottom) of Lane 1. B) DNA would be predominantly relaxed and would be found in the band seen in the positive pole (bottom) of Lane 1. C) DNA would be highly supercoiled and would be found in the band seen in the negative pole (top) of Lane 1. D) DNA would be predominantly relaxed and would be found in the band seen in the negative pole (top) of Lane 1. E) DNA would be both relaxed and supercoiled, so it would appear in a pattern similar to Lane 2.
