The correct Answer is:
To solve the question, we need to identify the correct term that describes the transfer of DNA fragments from a donor bacterial cell to a receptor bacterial cell through the medium. Here’s a step-by-step breakdown: ### Step 1: Understand the Options The options given are: 1. Translation 2. Transcription 3. Transduction 4. Transformation ### Step 2: Define Each Process - **Translation**: This is the process where proteins are synthesized from an RNA template. It does not involve DNA transfer between bacterial cells. - **Transcription**: This is the process where RNA is synthesized from a DNA template. Like translation, it does not involve the transfer of DNA between cells. - **Transduction**: This is a method of horizontal gene transfer where DNA is transferred from one bacterium to another via a virus (bacteriophage). This process involves a viral vector. - **Transformation**: This is another method of horizontal gene transfer where a bacterial cell takes up free DNA fragments from its environment and incorporates them into its own genome. This process does not require a virus. ### Step 3: Identify the Correct Answer Given the definitions: - The question specifically asks about the transfer of DNA fragments from a donor to a receptor bacterial cell through the medium. This description matches **transformation**, where the receptor cell directly takes up DNA from the environment. Thus, the correct answer is **option 4: Transformation**. ### Final Answer: The transfer of DNA fragments from a donor to receptor bacterial cell through the medium is called **Transformation**. ---
