Question
Organic compounds first evolved in earth required for origin of life were
- Urea and amino acids
- Proteins and nucleic acids
- Proteins and amino acids
- Urea and nucleic acids
The correct answer is: Proteins and nucleic acids
In the process of evolution smaller and simpler organic compounds gradually started combining among themselves to from complex organic compounds. The amino acids combines to form polypeptide and proteins while the purine and pyrimidines combine to form nucleotides and ultimately nucleic acids.
