The correct sequence of the steps of the lytic cycle is

  • A. release, assembly, biosynthesis, penetration, attachment
  • B. attachment, penetration, biosynthesis, assembly, release
  • C. biosynthesis, attachment, release, penetration, assembly
  • D. penetration, release, attachment, assembly, biosynthesis

Explanation

The phage first attaches by its tail fibres, injects its DNA, then commandeers the host to make viral parts, assembles complete particles and finally releases them by lysing the cell. Any sequence that starts later in the list reverses cause and effect.
