A) The discovery that retroviruses have an enzyme that catalyzes DNA synthesis from RNA
B) Evidence of the early emergence on Earth of chemical reactions that resulted in monomers

D) Evidence of the prebiotic chemical generation of cell-like compartments
E) The chemical traces of life found on meteorites

Question

Quizplus · Accepted Answer

The discovery of retroviruses, which have an enzyme that can convert RNA into DNA, provides evidence that RNA could have evolved into DNA over time.

Answer: B
 The emergence of monomers on early Earth suggests that the building blocks of RNA and DNA were present and could have led to the evolution of DNA from RNA.

Answer: D
 The prebiotic generation of cell-like compartments provides evidence that early cells could have existed that could have evolved RNA into DNA over time.

Option C and E are not relevant to support the hypothesis that DNA could have evolved from RNA.
