What is protoplast fusion in bacterial studies?

• A. Removing cell walls from two bacteria allows them to fuse
• B. Introducing foreign DNA to enhance bacterial properties
• C. Creating a protective layer for bacteria
• D. Inhibiting bacterial growth through environmental changes

Answer: (A)

Protoplast fusion refers to the process of combining two bacterial cells by first removing their cell walls to create protoplasts, which are the resulting cells that consist solely of the plasma membrane and the internal cellular components. This fusion occurs in a controlled environment where the absence of cell walls allows the membranes of the two protoplasts to come into close proximity and ultimately mix, resulting in a hybrid cell that can exhibit characteristics of both parent bacterial types. This technique is particularly valuable in genetic studies and biotechnological applications, as it enables the exchange of genetic material between different strains of bacteria that may not naturally be compatible. Protoplast fusion is used in various applications such as developing new strains with desirable traits, studying genetic recombination, and even in the production of antibiotics. The process does not involve introducing foreign DNA directly into the cells, which distinguishes it from the method described in the other option about enhancing bacterial properties. Furthermore, it does not create a protective layer or inhibit bacterial growth, which are unrelated concepts to the fundamental process of protoplast fusion. Thus, the accuracy of option A clearly highlights the essence of what protoplast fusion entails in bacterial studies.
