Question

According to the RNA world hypothesis, RNA acted as the genetic material and catalyzed reactions in ancient cells. What conclusion can you draw from this?

A. This implies that RNA can catalyze any chemical reaction that enzymes catalyze.
B. This implies that DNA and proteins evolved after RNA.
C. This implies that if a cell has a problem with its DNA, its RNA can compensate for the damaged DNA.
D. This implies that DNA and proteins aren't essential in cells today.

Answer 1

This implies that DNA and proteins evolved after RNA.

Step-by-step explanation:

Answer 2

Answer: B

Explanation: RNA world theory implies that DNA and protein evolved after RNA. Some evidence suggests RNA enzymes can catalyse reactions that are essential for life, example, ribosomes that are composed of RNA primarily. And ribonucleotide moiety in many enzymes.
