T4 infects Escherichia coli of the human gut and bursts the cell open. Which replication cycle is that?

1. A bacteriophage infection that yields new virions is called productive. 2. If those virions are released by bursting the cell, the virus is replicating by the lytic cycle. 3. T4 is the named example of a lytic bacteriophage, and it infects Escherichia coli of the human intestinal tract. 4. In the lysogenic cycle the phage genome joins the host genome instead of bursting the cell, so that option is the opposite case. _Source: OpenStax Biology (1st ed., CC BY 4.0), Ch 21 "Viruses", section 21.2 Virus Infections and Hosts_
