Verified step by step guidance

Understand the concept of bacterial conjugation: Conjugation is a process of horizontal gene transfer between bacteria, where genetic material is transferred from one bacterium to another through direct contact.

Identify the key components involved in conjugation: The donor cell typically contains a plasmid known as the F (fertility) factor, which facilitates the formation of a pilus, a bridge-like structure that connects the donor and recipient cells.

Recognize the role of physical contact: The pilus is essential for bringing the two bacterial cells into close proximity, allowing the transfer of genetic material. This physical contact is a defining characteristic of conjugation.

Evaluate the statement: Given that physical contact is necessary for the formation of the pilus and subsequent transfer of genetic material, the statement that bacterial cells must physically contact each other for conjugation to occur is true.

Conclude with the understanding that without physical contact, the process of conjugation cannot take place, as the pilus cannot form and genetic material cannot be transferred.
