There is no DNA in

Options

A. mature RBC.
B. mature spermatozoan
C. root hair
D. antipodal cells.

Answer

To solve the question "There is no DNA in," we need to identify which of the given options does not contain DNA. Let's analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding DNA Presence**:
- DNA (Deoxyribonucleic Acid) is the genetic material found in the nucleus of cells in most living organisms.

2. **Analyzing the Options**:
- **Option 1: Mature RBCs (Red Blood Cells)**:
- Mature RBCs in mammals (except camels) do not have a nucleus.
- Since DNA is located in the nucleus, the absence of a nucleus means mature RBCs do not contain DNA.
- Therefore, mature RBCs are a strong candidate for the answer.

- **Option 2: Mature Spermatozoon**:
- Mature sperm cells (spermatozoa) do contain a nucleus.
- The nucleus in sperm cells houses DNA, so this option does contain DNA.

- **Option 3: Root Hair**:
- Root hairs are extensions of root cells and are part of living cells that contain a nucleus.
- Since they have a nucleus, root hairs also contain DNA.

- **Option 4: Antipodal Cells**:
- Antipodal cells are found in the embryo sac of flowering plants and have a nucleus.
- As they contain a nucleus, they also contain DNA.

3. **Conclusion**:
- After analyzing all options, the only option that does not contain DNA is **Option 1: Mature RBCs**.

### Final Answer:
**Mature RBCs (Red Blood Cells)** do not contain DNA.
