Question

Which among the following is most likely the earliest event according to chemical theory of the origin of life?

• A. Formation of protobionts
• B. Synthesis of organic monomers
• C. Synthesis of organic polymers
• D. Formation of DNA based genetic system

Answer 1

The correct option is B Synthesis of organic monomers

According to Oparin and Haldane, chemical evolution occurred in four stages.

In the first stage of chemical evolution, molecules in the primitive environment formed simple organic substances, such as amino acids, which were present in their monomeric form.

So, the correct option is 'Synthesis of organic monomers'.
