Question

Which of the following is the correct sequence of events in the origin of life?

I. Formation of protobionts

II. Synthesis of organic molecules

III. Synthesis of organic polymers

IV. Formation of DNA-based genetic system

• A. II, III, I, IV
• B. II, III, IV, I
• C. I, II, III, IV
• D. I, III, II, IV

Answer 1

The correct option is A II, III, I, IV

The sequence of events in the origin of life is as follows:

The organic monomers were synthesised first and then the formation of the organic polymers took place. All these organic compounds were then aggregated together and surrounded by a feeble membrane. This structure was known as the "protobiont". Much more complex DNA-based genetic system evolved after that.
