Assertion :
Reptitive sequences make up very large portion of human genome
Reason Reptitve sequence do not have direct coding functions in the genome.

Options

A. Assertion and reason both are correct statements the reason is the correct explanation of the assertion.
B. Assertion and reason both are correct statements the reason is not the correct explanation of the assertion.
C. Assertion is true but reason is false statement.
D. Assertion is false but reason is true statement.

Answer

To analyze the assertion and reason provided in the question, we can break down the solution into the following steps:

### Step 1: Understand the Assertion
The assertion states that "Repetitive sequences make up a very large portion of the human genome."
- **Explanation**: Repetitive sequences are indeed a significant part of the human genome, accounting for a substantial percentage of the total DNA. These sequences can be classified into various types, including satellite DNA, mini-satellites, and micro-satellites, among others.

### Step 2: Understand the Reason
The reason states that "Repetitive sequences do not have direct coding functions in the genome."
- **Explanation**: This statement is also true. Repetitive sequences typically do not code for proteins. Instead, they may play roles in structural functions, regulation of gene expression, or serve as spacers in the genome.

### Step 3: Evaluate the Relationship Between Assertion and Reason
- **Analysis**: While both the assertion and reason are correct statements, the reason does not provide a direct explanation for the assertion. The assertion is about the proportion of repetitive sequences in the genome, while the reason discusses their lack of coding function, which does not explain why they comprise a large portion of the genome.

### Step 4: Conclusion
Based on the analysis:
- Both the assertion and reason are correct.
- However, the reason is not the correct explanation for the assertion.

### Final Answer
The correct conclusion is that both the assertion and reason are correct, but the reason does not correctly explain the assertion.
