Primitive type of DNA transfer occurs during sexual reproduction in

Options

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

Answer

To solve the question regarding the primitive type of DNA transfer that occurs during sexual reproduction, we can follow these steps:

### Step 1: Understand the Context of the Question
The question is asking about a primitive type of DNA transfer during sexual reproduction. It is important to identify what organisms exhibit this type of reproduction.

**Hint:** Consider which organisms are known for primitive forms of reproduction.

### Step 2: Identify the Organisms Involved
In the context of biological classification, we need to focus on organisms that reproduce sexually and can transfer DNA in a primitive manner. Bacteria are known for their unique methods of genetic exchange.

**Hint:** Recall the characteristics of bacteria and their reproduction methods.

### Step 3: Recognize the Methods of DNA Transfer
In bacteria, there are three primary methods of DNA transfer:
1. **Conjugation** - direct transfer of DNA between two bacteria.
2. **Transformation** - uptake of free DNA from the environment.
3. **Transduction** - transfer of DNA via a virus.

**Hint:** Think about how bacteria exchange genetic material compared to more complex organisms.

### Step 4: Conclude the Answer
Given that the question specifies a primitive type of DNA transfer during sexual reproduction, the correct answer is **bacteria**. This is because bacteria utilize these primitive mechanisms for genetic exchange, which is not seen in higher organisms to the same extent.

**Hint:** Focus on the term "primitive" and how it relates to the methods of reproduction in different organisms.

### Final Answer:
The primitive type of DNA transfer occurs during sexual reproduction in **bacteria**.
