The virus gets into a host cell by in the following manner:

  1. The virus attaches itself to the host cell receptors present on its surface by means of specific proteins present on its surface called Spikes.
  2. After the attachment, the cell wall of the host cell is digested by lysozyme enzyme released from the tail of the virus particle (phage). Lysozyme drills a hole in the mucopeptide layer of the cell wall.
  3. The contraction of the tail sheath pushes the core tube through the cell wall of the host cell and the DNA gets injected into the host cell.
  4. The capsid or protein coat remain outside the host cell while only the DNA molecule is injected into the cell.
