Question

Which of the following is NOT mentioned as evidence supporting the RNA World Hypothesis?

Options

• DNA being more abundant than RNA in living cells

• Presence of regulatory RNAs in modern cells

• Discovery of ribozymes

• Ribosome containing catalytic RNA

Answer 1

All the options except 'DNA being more abundant than RNA in living cells' are explicitly mentioned as evidence for the RNA World Hypothesis. In fact, RNA is found abundantly in all living cells and is structurally related to DNA, supporting the hypothesis rather than contradicting it.
