Distinguish between the lytic and lysogenic cycles of viruses.(1 point) Responses The lytic cycle involves the merging together of the viral and host genomes. The lytic cycle involves the merging together of the viral and host genomes. The viral genome is only injected into the cell during the lytic cycle. The viral genome is only injected into the cell during the lytic cycle. The viral genome incorporates into the host genome during the lysogenic cycle. The viral genome incorporates into the host genome during the lysogenic cycle. The lysogenic cycle involves newly replicated virus bursting from the cell.
The lytic cycle and the lysogenic cycle are two different ways in which viruses can reproduce and infect host cells.
In the lytic cycle, the viral genome is injected into the host cell. Once inside, the viral genome takes over the host cell's machinery and directs it to produce viral proteins and replicate the viral genome. These newly produced viral components then assemble to form new viruses, which eventually burst out of the host cell, destroying it in the process. This cycle is characterized by the quick and immediate replication of the virus, leading to the rapid production of new viral particles and the destruction of the host cell.
In contrast, the lysogenic cycle involves the viral genome incorporating into the host genome. Instead of immediately taking control of the host cell's machinery, the viral DNA becomes integrated into the host cell's DNA and becomes a part of it. The host cell then continues to divide and replicate normally, with the viral DNA being passed on to each daughter cell during cell division. This cycle allows the virus to remain dormant within the host cell, without causing immediate harm. However, under certain conditions, such as stress or changes in the host environment, the viral DNA can be activated and enter the lytic cycle, leading to the production of new viruses and the destruction of the host cell.
