Question

Arrange the following events of chemical evolution in proper sequence.

i. formation of nucleic acid

ii. formation of eobionts

iii. formation of protocell

iv. formation of complex organic compounds

• A. i \(\rightarrow\) iii \(\rightarrow\) iv \(\rightarrow\) ii
• B. iv \(\rightarrow\) i \(\rightarrow\) iii \(\rightarrow\) ii
• C. ii \(\rightarrow\) iii \(\rightarrow\) i \(\rightarrow\) iv
• D. ii \(\rightarrow\) i \(\rightarrow\) iii \(\rightarrow\) iv

Hint:

Complex organic compounds come first, then nucleic acids, then protocells and finally eobionts.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept
Chemical evolution describes how life-like systems arose from simple molecules.

Step 2: Order
First complex organic compounds form (iv). Next nucleic acids form (i).

Step 3: Later steps
Then protocells form (iii) and finally eobionts appear (ii).

Step 4: Compare the options
The sequence is iv \(\rightarrow\) i \(\rightarrow\) iii \(\rightarrow\) ii.

Final Answer:
The correct sequence starts with complex organic compounds and ends with eobionts. \[ \boxed{\text{(B) }\text{iv}\rightarrow\text{i}\rightarrow\text{iii}\rightarrow\text{ii}} \]
