Question

Which of the following states a hypothesis that has been proposed concerning RNA's role in the origin of life on Earth?

A.Self-replicating RNA molecules able to bind to other molecules and carry out unique chemical reactions were the precursors to today's biomolecules.

B.A prebiotic soup of amino acids and RNA molecules provided the materials necessary for early cell membranes to form.

C.Polypeptide chains emerged as the first biopolymers, which then provided templates for the evolution of DNA and RNA strands.

D.RNA evolved after self-replicating DNA molecules established the basic pattern of base sequence transfer.
