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?
Question 5 options:

A)

This implies that if a cell has a problem with its DNA, its RNA can compensate for the damaged DNA.

B)

This implies that RNA can catalyze any chemical reaction that enzymes catalyze.

C)

This implies that DNA and proteins evolved after RNA.

D)

This implies that DNA and proteins aren't essential in cells today.

Answer 1

The correct conclusion you can draw from the RNA world hypothesis is:

C) This implies that DNA and proteins evolved after RNA.

The RNA world hypothesis suggests that early life forms used RNA both for storing genetic information and for catalyzing biochemical reactions, indicating that RNA predates DNA and proteins in the evolution of life.
