DNA taken in via conjugation must be integrated into the host cell genome to be used. True or false? Explain your reasoning.
Homework Answers
False
DNA taken in via conjugation is generally a plasmid and it generally provides genetic advantages such as antibiotic resistance to bacteria. Plasmids are capable for independent replication and are not not dependent on bacteria DNA chromosome for their replication.

Which of the following is NOT true about bacterial conjugation An F factor drives replication and transfer of a conjugative plasmid The genome of the bacterial chromosome in the donor cells is altered through ectopic recombination Transfer is mediated by a tube-like pilus formed between the adjacent cells Mating cells often break apart before transfer of the entire bacterial chromosome. The transferred DNA can be incorporated in the recipient cell bacterial chromosome via homologous recombination.
