Which viral replication cycle is represented in part A of this diagram? O A. Dormant cycle
OB. Replication cycle
C. Lysogenic cycle
O D. Lytic cycle

The correct answer is - option D. lytic cycle.

Explanation:

The lytic cycle is one of the two viral reproduction cycle. Generally, it is the major reproduction cycle. In this cycle reproduction of the viruses takes place inside the host cell and produce more viruses. In the production of the more viruses the host cell and it''s destruction takes place in the end. The 5 steps that takes place are as follows:

1- attachment - viruses attach to the cell.

2-penetration- only nucleic acid or genetic material is injected into the host cell through the hole made by the tail fibers and enzymes.

3- synthesis - replication of viral nucleic acid and protein and envelope.

4- assembly - assembling of the new viruses formed.

5- release.

Thus, the correct answer is - option D.

c. heat from the poles back down towards the equator.
