Question

Choose the correct answers from the alternatives given .
Evolution of the DNA $\to$ RNA $\to$ protein system was a milestone because the protocell

• A. needed energy to grow
• B. could now reproduce
• C. was a heterotrophic fermenter
• D. all of these

Answer 1

The correct option is B could now reproduce

Protocells are polypeptides synthesized by heating a mixture of amino acids from 160°C to 210°C for several hours. However, after the origin of life in the form of a giant, self- replicating aggregates of macromolecules like nucleic acids (DNA, RNA) and proteins, biological evolution started. It resulted in the formation of various complex biological forms that we can see today. So, the correct option is "could now reproduce".
