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 solve the question regarding the features associated with the incipient nucleus of Monera, we will analyze each feature provided in the question.

### Step-by-Step Solution:

1. **Understanding Monera**:
- Monera is a kingdom that includes all unicellular organisms, primarily bacteria, which are prokaryotic. Prokaryotes do not have a well-defined nucleus; instead, they have an incipient nucleus, which refers to their genetic material that is not enclosed by a nuclear membrane.

2. **Analyzing Each Feature**:
- **Naked DNA**:
- This is correct. In prokaryotes, the genetic material is not enclosed in a membrane, thus it is referred to as naked DNA.
- **RNA**:
- This is also correct. Monera contains RNA as part of its cellular machinery.
- **Non-histonic proteins**:
- This is incorrect. Prokaryotes do not have non-histonic proteins; they primarily use histones in some archaea, but not in bacteria.
- **Histonic proteins**:
- This is incorrect for bacteria. While some prokaryotes may have histone-like proteins, true histones are not present in Monera.
- **Linear ss-DNA**:
- This is incorrect. Prokaryotes typically have circular double-stranded DNA, not linear single-stranded DNA.
- **Circular ds-DNA**:
- This is correct. The genetic material in Monera is usually circular and double-stranded.

3. **Counting the Correct Features**:
- From the analysis, the features associated with the incipient nucleus of Monera are:
- Naked DNA (Correct)
- RNA (Correct)
- Circular ds-DNA (Correct)
- Therefore, there are 3 features associated with the incipient nucleus of Monera.

### Final Answer:
The number of features associated with the incipient nucleus of Monera is **3**.
