DNA is mainly found in

Options

A. Nucleous
B. Nucleus only
C. Cytolasm only
D. None of these

Answer

**Step-by-Step Solution:**

1. **Understanding DNA**: DNA stands for deoxyribonucleic acid and is the genetic material found in cells. It carries genetic information from one generation to the next.

2. **Location of DNA**: The primary location of DNA in eukaryotic cells is the nucleus. The nucleus is a membrane-bound organelle that houses the cell's genetic material.

3. **Other Locations**: While the nucleus is the main site for DNA, certain organelles such as mitochondria and chloroplasts also contain their own DNA. This DNA is distinct from the nuclear DNA and is involved in the organelle's functions.

4. **Exclusion of Other Areas**: DNA is not found in the nucleolus (a structure within the nucleus) or in the cytoplasm. The nucleolus is involved in ribosome production and does not contain DNA.

5. **Conclusion**: Therefore, the correct answer to the question "DNA is mainly found in" is the nucleus.

**Final Answer**: DNA is mainly found in the nucleus.
