Researchers Use the Denaturation Temperatures of Hybrid Double Helices to Compare

Multiple Choice

Researchers use the denaturation temperatures of hybrid double helices to compare evolutionary relatedness. Complementary strands denature at 95 degrees. A researcher engineers a hybrid strand from two species and it denatures at 93 degrees. What does this mean?

A) The hybrid double helices are more complementary than the non-hybrid.
B) The hybrid double helices are less complementary than the non-hybrid.
C) The species are more closely related than any other two species.
D) The hybrid strands' base pairs had fewer mismatches.
