Answer

To solve the question regarding the correct sequence of chemical formation on early Earth, we can break down the process into several key steps based on the information provided in the video transcript.

### Step-by-Step Solution:

1. **Understanding Early Earth Conditions**:
- Early Earth had a reducing atmosphere composed of simple inorganic molecules such as ammonia (NH₃), methane (CH₄), water vapor (H₂O), and hydrogen (H₂).
- These conditions were conducive to chemical reactions that could lead to the formation of organic molecules.

2. **Formation of Simple Organic Molecules**:
- Under high temperatures and the influence of energy sources (like lightning or UV radiation), simple inorganic molecules reacted to form simple organic molecules.
- The simplest organic molecules formed include amino acids, sugars, and nucleotides.

3. **Formation of Complex Organic Molecules**:
- The simple organic molecules then underwent further reactions to form more complex organic molecules.
- This includes the formation of proteins from amino acids, carbohydrates from simple sugars, and nucleic acids from nucleotides.

4. **Sequence of Formation**:
- According to the information provided, the correct sequence of formation is:
1. **Proteins** (formed from amino acids)
2. **Carbohydrates** (formed from simple sugars)
3. **Nucleic Acids** (formed from nucleotides)

5. **Conclusion**:
- Based on the above steps, the correct sequence of chemical formation on early Earth is: **Proteins → Carbohydrates → Nucleic Acids**.

### Final Answer:
The correct sequence during the formation of chemicals on early Earth is: **Proteins → Carbohydrates → Nucleic Acids**.
