Answer #1

B. Prophage

  • Prophage is term used to describe the integrated product of host and phage DNA. Lysogenic phage are capable of forming prophage
  • Virulent phage is one that uses only lytic cycle. In lytic cycle the phage DNA is separate from host DNA (NOT integrated) and it replicate. Progeny phage are released from destruction of host cell.
