Which of the following is true concerning a lysogenic viral replication cycle?
A
The viral particles are assembled in the cytoplasm of the host cell.
B
The virus uses reverse transcriptase to convert its RNA into DNA.
C
The virus immediately begins to replicate and lyse the host cell.
D
The viral DNA integrates into the host genome and can remain dormant for long periods.
Verified step by step guidance1
Understand the lysogenic cycle: In the lysogenic cycle, the viral DNA is integrated into the host cell's genome, where it can remain inactive or dormant for extended periods.
Differentiate between the lysogenic and lytic cycles: The lytic cycle involves immediate replication and destruction of the host cell, whereas the lysogenic cycle involves integration into the host genome without immediate destruction.
Consider the role of reverse transcriptase: This enzyme is typically associated with retroviruses, which convert RNA into DNA, but not all lysogenic viruses use reverse transcriptase.
Recognize the dormancy aspect: In the lysogenic cycle, the viral DNA can remain dormant, meaning it does not immediately cause harm or replicate within the host cell.
Identify the correct statement: The statement 'The viral DNA integrates into the host genome and can remain dormant for long periods' accurately describes the lysogenic cycle.
