The cell’s metabolic machinery, directed by phage DNA, produces phage proteins and nucleotides from the cells degraded DNA are used to make copies of the phage genome.
The phage then directs production of an enzyme that digests the cell.
The empty capsid of the phage is left as a ghost outside the cell
