What is bacterial conjugation? A. Bacterial conjugation is a method by which bacteria communicate with each other to coordinate group behaviour. B. Bacterial conjugation is a process where bacteria absorb DNA from their surrounding environment for genetic transformation. C. Bacterial conjugation is a process where bacteria exchange genetic material (DNA) through a direct physical connection, leading to genetic diversity and enhancing survival chances. D. Bacterial conjugation is a type of simple bacterial reproduction where a single bacterium divides into two identical cells.

What does bacterial growth on a plate containing a particular trait (such as antibiotic resistance) after a bacterial conjugation experiment indicate? A. The bacterial colonies have acquired the trait from the F- strain (recipient). B. The bacterial colonies have resisted the trait and not undergone conjugation. C. The bacterial colonies have undergone mutation and developed the trait on their own. D. The bacterial colonies growing on the plate have likely undergone conjugation and acquired the desired trait from the F+ strain (donor).
