Question

____ are involved in the transfer of genetic information from one bacterial cell to another.
a) flagella
b) pili
c) cilia
d) ribosomes

Explanation:

Pili are hair - like structures on the surface of bacteria. In the process of conjugation (a form of genetic transfer in bacteria), the donor bacterium uses a pilus (also called a sex pilus) to attach to the recipient bacterium and transfer genetic material (usually a plasmid). Flagella are for locomotion. Cilia are not typically found in bacteria (they are more common in eukaryotic cells like some protozoa). Ribosomes are involved in protein synthesis, not genetic transfer.

Answer:

B. Pili
