You have isolated DNA from a Three-toed tree sloth. As you increase the temperature of the DNA isolated from the Three-toed tree sloth, you find that the UV absorption increases dramatically at temperatures above 85°C and levels off above 95°C. The midpoint of the transition is 90°C. You have observed this behavior before with DNA samples from other organisms. The melting temperature (Tm) of nuclear DNA from a Kangaroo is 87°C, and you know that kangaroo DNA is 52% G+C and 48% A+T. Which statement below does not correctly explain how the DNA content (in terms of the mole percentage of the bases) compare between the Three-toed tree sloth and the Kangaroo? O The Three-toed tree sloth's DNA has a higher % of A-T base pairs than G-C base pairs. Kangaroo DNA has a lower G-C mole percentage than the Three-toed tree sloth. O Kangaroo DNA has a higher A-T mole percentage than the Three-toed tree sloth. The melting temperature for kangaroo DNA is 87°C vs. 90°C for the three-toed tree sloth.
