Question

The sequence of origin of life may be considered as

• A. Amino acid $\to$ Protein $\to$ Chlorophyll
• B. Chlorophyll $\to$ Starch $\to$ Glycogen
• C. Nucleic acid $\to$ Amino acid $\to$ Chlorophyll
• D. Chlorophyll $\to$ Nucleic acid $\to$ Amino acid

Answer 1

The correct option is A Amino acid $\to$ Protein $\to$ Chlorophyll

According to spontaneous generation of life, the sequence of origin of life may be considered as amino acid, protein and chlorophyll. In primitive atmosphere of earth, nitrogen, hydrogen, ammonia, methane, carbon mono-oxide and water were present. The spontaneous interaction of these molecules formed more complex organic molecules such as amino acids. Complex marcromolecule protein was formed from polymerization of amino acids. Random combinations of these proteins along with other macromolecules led to formation of chlorophyll.

Thus, the correct answer is option A.
