Question 1

(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.
