How many of the given features are associated with incipient nucleus of Monera: Naked DNA,RNA,Non-histonic proteins,Histonic proteins,Linear ss-DNA, Circular ds-DNA.

Options

A. 3
B. 6
C. 4
D. 2

Answer

To determine how many features are associated with the incipient nucleus of Monera, we will analyze each feature listed in the question:

1. **Naked DNA**: Monera, which includes prokaryotic organisms like bacteria, typically has naked DNA. This means that the DNA is not associated with histone proteins, which is a characteristic of prokaryotic cells.
- **Associated**: Yes

2. **RNA**: Monera does contain RNA, as it is essential for protein synthesis and other cellular functions.
- **Associated**: Yes

3. **Non-histonic proteins**: These proteins are indeed present in Monera. Non-histonic proteins are associated with the organization of DNA in prokaryotes.
- **Associated**: Yes

4. **Histonic proteins**: While prokaryotes like Monera do not typically have histones associated with their DNA, some may have proteins that are similar to histones. However, in general, histones are not a feature of Monera.
- **Associated**: No

5. **Linear ss-DNA**: Monera does not have linear single-stranded DNA as its genetic material; instead, it primarily has circular DNA.
- **Associated**: No

6. **Circular ds-DNA**: This is a characteristic feature of Monera. Their genetic material is usually found in the form of circular double-stranded DNA.
- **Associated**: Yes

Now, let's summarize the features that are associated with the incipient nucleus of Monera:

- Naked DNA: Yes
- RNA: Yes
- Non-histonic proteins: Yes
- Histonic proteins: No
- Linear ss-DNA: No
- Circular ds-DNA: Yes

Counting the features that are associated:
- Naked DNA: 1
- RNA: 1
- Non-histonic proteins: 1
- Circular ds-DNA: 1

Total associated features = 4

Thus, the answer is **4**.
