Question
How were protobionts formed with the help of nucleic acids during chemical evolution?
✓
Answer
- By the reaction between phosphoric acid, sugar and nitrogenous bases (purines and pyrimidines), nucleotides may have been formed.
- These nucleotides joined together to form nucleic acids such as RNA and DNA.
- Nucleic acids acquired self-replicating ability which is a fundamental property of living form.
- They later formed protobionts. They were the first form of life formed by nucleic acids along with inorganic and organic molecules.
- Protobionts were the prebiotic chemical aggregates having some properties of living system. Aggregation of organic molecules due to coacervation formed these protobionts.
