A researcher is studying two solutions of DNA. Solution A has a higher percentage of G-C base pairs than Solution B. Which of the following is true regarding Solution A?
- It is more susceptible to UV-induced photodamage than Solution B is.
- The two complementary DNA strands run parallel rather than in antiparallel fashion.
- It has a lower melting temperature since G-C pairs form fewer hydrogen bonds than A-T pairs.
- It has a higher melting temperature due to the three hydrogen bonds between G and C
