Question

According to spontaneous generation theory, the sequence of origin of life may be considered as

• A. Amino acid --> protein --> chlorophyll
• B. Chlorophyll --> starch --> glycogen
• C. Nucleic acid --> amino acid --> chlorophyll
• D. Chlorophyll --> nucleic acid --> amino acid

Answer 1

The correct option is A Amino acid --> protein --> chlorophyll

Complex organic bio-polymers were produced by polymerisation of simple starting monomeric organic units. Amino acids were apparently most important biomolecules produced in the ancient earth. Amino acids polymerised on clay surfaces to form proteins and Chlorophyll came much later that's how autotrophs evolved much later and primitive organisms were all heterotrophs.
