Question 1 (1 point): While snooping around Area 51 in New Mexico, you manage to isolate an alien bacterium and decide to take it back to the lab for study. When you mix an extract of the alien bacterial cells with some relaxed circular DNA, you discover that the DNA quickly becomes supercoiled.

A. Would the alien enzyme responsible for the supercoiling be classified as a topoisomerase I or a topoisomerase II, using Earth enzymes as a reference? _________________________

B. What substrate (or alien equivalent) would this enzyme require in addition to DNA? _________________________

C. Further study of the alien enzyme reveals that it overwinds DNA rather than underwinds it like terrestrial enzymes. Would the supercoils introduced into your DNA be positive or negative? _________________________
