Nucleoid
C
Flagellum
D
Ribosome
Verified step by step guidance
1
Understand the concept of conjugation in prokaryotes: Conjugation is a process where genetic material is transferred between bacterial cells through direct contact.
Identify the structures involved in conjugation: The key structure used by prokaryotes for conjugation is the pilus, specifically the sex pilus.
Differentiate between the given options: Pilus, Nucleoid, Flagellum, and Ribosome. The pilus is a hair-like appendage that facilitates the transfer of DNA during conjugation.
Clarify the role of the pilus: The pilus forms a bridge between two bacterial cells, allowing the transfer of plasmid DNA from the donor to the recipient cell.
Conclude why the pilus is the correct answer: The pilus is specifically designed for the purpose of conjugation, unlike the other structures listed, which serve different functions in the cell.
