  • Conjugation can only transfer plasmids, not chromosomal genes.
  • Conjugation involves the transfer of genetic material from a recipient strain to a donor strain.
  • Conjugation occurs between two bacterial cells that are not in close contact.
  • The F factor is a plasmid that carries the genes for conjugative transfer. (correct)
  • What is the function of the sex or conjugation pilus in conjugation?

  • To produce restriction enzymes.
  • To restrict the incorporation of foreign DNA into bacterial genomes.
