Question

Which of the following act as an evidence for the RNA world hypothesis?
  1. Microfossils
  2. Ribozymes are RNA molecules that have been shown to catalyze reactions
  3. Some modern prokaryotes use RNA without using DNA.
  4. The atmosphere of primitive earth favored the production of nucleic acids over other macromolecules.

A
Microfossils
B
Some modern prokaryotes use RNA without using DNA.
C
The atmosphere of primitive earth favored the production of nucleic acids over other macromolecules.
D
Ribozymes are RNA molecules that have been shown to catalyze reactions
Solution
Verified by Toppr

The discovery of ribozymes supported a hypothesis, known as the RNA World Hypothesis, that earlier forms of life may have relied solely on RNA to store genetic information and to catalyze chemical reactions
The presence of ribosomes that assemble proteins are also a kind of ribozymes and thus this all supported the RNA world hypothesis.

So, the correct option is 'Ribozymes are RNA molecules that have been shown to catalyze reactions'
