What process allows bacteria to take up naked DNA from their environment and incorporate it into their genome?

• A. Conjugation
• B. Transduction
• C. Transformation
• D. Binary fission

Answer: (C)

The process that allows bacteria to take up naked DNA from their environment and incorporate it into their genome is transformation. In transformation, bacteria can absorb free DNA released from other bacterial cells into their surroundings, which may occur after the cells lyse and release their genetic material. Once inside the competent bacterial cell, this naked DNA can recombine with the bacterium’s own DNA, leading to genetic changes, including the acquisition of new traits such as antibiotic resistance or metabolic capabilities. This mechanism is a natural process utilized by many bacteria and is a key area of study in genetic engineering and biotechnology, as it can facilitate the introduction of specific genes into bacterial populations for research or practical applications.
