Which of the following is not correct about DNA?

Options

A. It occurs in the cytoplasm of the cell.
B. The sugar present is 2-deoxy D(-) ribose.
C. It has a double strand a-helix.
D. It has property of replication.

Explanation

To determine which statement is not correct about DNA, we will analyze each of the given options step by step.

### Step 1: Analyze the first statement
**Statement:** DNA occurs in the cytoplasm of the cell.
**Evaluation:** This statement is **not correct**. DNA is primarily located in the nucleus of eukaryotic cells. In prokaryotic cells, DNA is found in the nucleoid region, not in the cytoplasm. Therefore, this statement is false.

### Step 2: Analyze the second statement
**Statement:** The sugar present in DNA is 2-deoxy-D-ribose.
**Evaluation:** This statement is **correct**. The sugar component of DNA is indeed 2-deoxy-D-ribose, which is a five-carbon sugar that lacks one oxygen atom compared to ribose.

### Step 3: Analyze the third statement
**Statement:** DNA has a double strand and a helical structure.
**Evaluation:** This statement is **correct**. DNA is known for its double-stranded helical structure, famously described by Watson and Crick.

### Step 4: Analyze the fourth statement
**Statement:** DNA has the property of replication.
**Evaluation:** This statement is **correct**. DNA has the ability to replicate itself, which is essential for cell division and the transmission of genetic information.

### Conclusion
After evaluating all the statements, we find that the first statement is the only one that is not correct. Therefore, the answer to the question is:

**Final Answer:** DNA occurs in the cytoplasm of the cell (Option A).
