Verified step by step guidance

Understand the concept of bacterial conjugation: Bacterial conjugation is a process where genetic material is transferred between bacterial cells through direct contact.

Identify the role of a bacteriophage: A bacteriophage is a virus that infects bacteria, but it is not involved in bacterial conjugation. Instead, it is involved in transduction, another form of genetic exchange.

Consider the environmental conditions: Bacterial conjugation does not require oxygen; it can occur in both aerobic and anaerobic conditions.

Examine the outcome of conjugation: Bacterial conjugation does not produce identical daughter cells. Instead, it results in genetic variation as DNA is exchanged between cells.

Conclude with the correct statement: The true statement about bacterial conjugation is that it involves the direct transfer of DNA between two bacterial cells.
