In the context of the temperate life cycle, what does the term 'lysogenic conversion' mean?
A
The transformation of viral RNA into DNA within the host cell.
B
The integration of viral DNA into the host genome, altering the host's characteristics.
C
The immediate production of new viral particles without integration into the host genome.
D
The destruction of the host cell due to viral replication.
Verified step by step guidance1
Lysogenic conversion is a process that occurs during the lysogenic cycle of a bacteriophage, where the viral DNA is integrated into the host cell's genome.
This integration of viral DNA into the host genome can lead to changes in the host cell's characteristics, as the viral genes may alter the expression of host genes.
Unlike the lytic cycle, where the virus immediately replicates and destroys the host cell, the lysogenic cycle allows the viral DNA to remain dormant within the host genome.
During lysogenic conversion, the host cell can continue to divide and replicate, passing the integrated viral DNA to its progeny, potentially leading to long-term changes in the host population.
Lysogenic conversion can result in new traits or abilities in the host organism, such as increased virulence or resistance to certain environmental factors, due to the expression of viral genes.
