Answer:
Lysogenic replication cycle is one unique process in T7 virus replication.
Explanation:
The T7 virus is a virus that attacks bacteria ( bacteriophage). Unlike other viruses (plants and animals viruses), it replicates within the host cell by means of two cycles: the lytic replication cycle and the lysogenic replication cycle.
Virulent phages replicate through the lytic replication cell and this lead to the death of the cell through cell lysis.
The lysogenic replication cycle involves bacteriophages known as temperate bacteriophages. Temperate bacteriophages can become part of a host chromosome forming a prophage. The prophage replicates with the formation of daughter cells with incorporated viral genetic materials until when induced to enter into the lytic stage thereby producing new viruses which then exit the host cell by cell lysis.
This process of incorporation into the host cell genome is known as lysogenic replication and is unique to the bacteriophages.
Viruses are neither living nor dead organisms. The viruses require a host to replicate. The virus follows the lysogenic or lytic cycle to replicate. The T7 virus follows the lysogenic replication pathway.
The T7 virus follows the lysogenic pathway, in which the nucleic acid of the bacteriophage is incorporated into the host genome. The T7 virus intervenes on the bacteriophage genome.
In the lysogenic cycle, bacteriophages can become part of the host genome. This genome is then known as prophage. Prophage replicates and forms the daughter cells with the altered genetic material of the host.
The new cells produced are released by the lytic cycle, in which the cell produces new cells by lysis.
Thus, the incorporation of the host cell genome in the bacteriophage via the lysogenic cycle is a unique feature of a virus, T7.
