Viruses that reproduce almost immediately after coming into contact with a host cell use which viral reproductive cycle?

A. lytic cycle

B. infectious cycle

C. lysogenic cycle

D. temperate cycle

The best answer is A.

The lytic cycle is considered the main cycle in viral replication. Once the viral DNA enters the cell, it transcribes itself into the host cell's messenger RNAs and uses them to direct the ribosomes.

The host cell's DNA is destroyed and the virus takes over the cell's metabolic activity and begins to use the cell's energy for its own propagation and within a short while, when the cell gets overcrowded with the viral progeny, the original virus releases enzymes to break the cell wall. The cell wall bursts. This process is called lysis. The new viruses are then released.
