What happens during the lytic cycle?
Veseljchak [2.6K]

In the lytic  cycle, a virus that has invaded and  entered a  cell takes over the cell's replication mechanism. The virus makes viral DNA and viral proteins.

The virus then lyses (breaks open) the cell membrane, allowing the newly  produced viruses to leave the now disintergrated host cell to infect  other new cells.

The lytic cycle is considered  the main method of viral replication. It is even more common than the lysogenic cycle. It has helped scientists understand better how the immune system responds  to pathogens.
