Select the correct set from the following statements with respect to the salient features of the human genome.
i. The human genome contains 3164.7 billion nucleotides.
ii. The function is unknown for over 50 % of the discovered gene.
iii. Less than 20% of the genome code for Proteins.
iv chromosomes -1 has the most genes ( 2968 ) and y has the fewest ( 231 ) .
V. The total number of genes estimated is 30,000.

Options

A. ii , iv , v
B. i,ii,iv
C. i,iii,v
D. i,iv,v

Answer

To solve the question regarding the salient features of the human genome, we will analyze each statement provided and determine its correctness.

### Step-by-Step Solution:

1. **Statement i**: "The human genome contains 3164.7 billion nucleotides."
- **Analysis**: This statement is incorrect. The human genome actually contains approximately 3.1647 billion nucleotides (not billion, but million).
- **Conclusion**: Incorrect.

2. **Statement ii**: "The function is unknown for over 50% of the discovered genes."
- **Analysis**: This statement is correct. It is estimated that the functions of more than 50% of the genes in the human genome are still unknown.
- **Conclusion**: Correct.

3. **Statement iii**: "Less than 20% of the genome codes for proteins."
- **Analysis**: This statement is incorrect. In reality, less than 2% of the human genome codes for proteins.
- **Conclusion**: Incorrect.

4. **Statement iv**: "Chromosome 1 has the most genes (2968) and Y has the fewest (231)."
- **Analysis**: This statement is correct. Chromosome 1 indeed has the highest number of genes, while the Y chromosome has the fewest.
- **Conclusion**: Correct.

5. **Statement v**: "The total number of genes estimated is 30,000."
- **Analysis**: This statement is correct. The estimated number of genes in the human genome is around 30,000.
- **Conclusion**: Correct.

### Summary of Findings:
- **Correct Statements**: ii, iv, v
- **Incorrect Statements**: i, iii

### Final Answer:
The correct set of statements regarding the salient features of the human genome includes statements ii, iv, and v.
