Primitive type of DNA transfer occurs during sexual reproduction in

Options

A. Bacteria
B. Fungi
C. Slime moulds
D. Cyanobacteria

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question asks about the primitive type of DNA transfer that occurs during sexual reproduction. We need to identify which organism exhibits this characteristic.

2. **Identifying the Organism:**
The organism in question is bacteria. Bacteria are known for their primitive cellular organization and reproduction methods.

3. **Types of Reproduction in Bacteria:**
While bacteria primarily reproduce asexually, they can also engage in processes that allow for genetic exchange, which is akin to sexual reproduction.

4. **Methods of DNA Transfer in Bacteria:**
There are three main methods through which bacteria can transfer DNA:
- **Conjugation:** This is a direct transfer of DNA from one bacterium to another through physical contact.
- **Transformation:** This involves the uptake of free DNA from the environment by a bacterium.
- **Transduction:** This is the transfer of DNA from one bacterium to another via a bacteriophage (a virus that infects bacteria).

5. **Focusing on Conjugation:**
The primitive type of DNA transfer during sexual reproduction in bacteria is most commonly associated with conjugation. In this process, a donor bacterium forms a physical connection with a recipient bacterium and transfers genetic material.

6. **Conclusion:**
Therefore, the primitive type of DNA transfer that occurs during sexual reproduction is primarily through conjugation in bacteria.

**Final Answer:**
Primitive type of DNA transfer occurs during sexual reproduction in bacteria, primarily through the process of conjugation.
