Protistan genome has

Options

A. membrane bound nuleoproteins embredded in cytoplasm
B. free nucleic acid aggregates
C. gene containing nucleoproteins condensed together in loose mass
D. nucleoprotein in direct contact with cell substance

Explanation

**Step-by-Step Solution:**

1. **Understanding Protistan Genome**: Protists are eukaryotic organisms, which means they have a defined nucleus that contains their genetic material. The genetic material in protists is organized as nucleoproteins, which are complexes of DNA or RNA with proteins.

2. **Identifying the Structure**: In protists, the genome is housed within a membrane-bound structure called the nucleus. This nucleus is embedded in the cytoplasm of the cell, which is characteristic of eukaryotic cells.

3. **Evaluating the Options**:
- **Option 1**: "Membrane bound nucleoproteins embedded in cytoplasm." This option correctly describes the structure of the protistan genome, as it is indeed membrane-bound and located within the cytoplasm.
- **Option 2**: "Free nucleic acid aggregates." This describes a characteristic of prokaryotes (like bacteria), where nucleic acids are not contained within a membrane-bound nucleus.
- **Option 3**: "Gene containing nucleoproteins condensed together in loose mass." This option is incorrect for protists, as their nucleoproteins are organized within a defined nucleus, not in a loose mass.
- **Option 4**: "Nucleoprotein in direct contact with the cell substances." This also describes a prokaryotic characteristic, as prokaryotic cells do not have a membrane-bound nucleus.

4. **Conclusion**: Based on the evaluation of the options, the correct answer is **Option 1: Membrane bound nucleoproteins embedded in cytoplasm**.
