Options

A. `{:("(i)","(ii)","(iii)","(iv)"),("5%","regulator ","DNA polymerase II ","DNA polymerase"beta):}`
B. `{:("(i)","(ii)","(iii)","(iv)"),("10%","regulator ","DNA polymerase I ","DNA polymerase"alpha):}`
C. `{:("(i)","(ii)","(iii)","(iv)"),("2%","inducer ","DNA polymerase I ","DNA polymerase"beta):}`
D. `{:("(i)","(ii)","(iii)","(iv)"),("50%","inducer ","DNA polymerase III ","DNA polymerase"alpha):}`

Answer

To solve the question, we will fill in the blanks step by step based on the information provided in the video transcript.

### Step-by-Step Solution:

1. **Blank (i)**: The question states that "Less than (i)____ of the genome represents structural genes that code for proteins." According to the transcript, it is mentioned that "only 2% of the genome represents structural genes that code for proteins." Therefore, the correct answer for blank (i) is:
- **Answer**: 2%

2. **Blank (ii)**: The next part of the question asks for a "Chemical substance that binds with repressor and converts it into a non-DNA binding state is (ii)_____." The transcript refers to the lac operon and mentions that the inducer that binds to the repressor is lactose. Therefore, the correct answer for blank (ii) is:
- **Answer**: Lactose

3. **Blank (iii)**: The question continues with "In prokaryotes, during replication RNA primer is removed by (iii)____." The transcript specifies that in prokaryotes, RNA primer is removed by DNA polymerase I. Therefore, the correct answer for blank (iii) is:
- **Answer**: DNA polymerase I

4. **Blank (iv)**: Finally, the question asks "whereas in eukaryotes it is removed by (iv)______." The transcript indicates that in eukaryotes, RNA primer is removed by DNA polymerase beta. Therefore, the correct answer for blank (iv) is:
- **Answer**: DNA polymerase beta

### Final Answers:
- (i) 2%
- (ii) Lactose
- (iii) DNA polymerase I
- (iv) DNA polymerase beta
