What do viruses need to reproduce?
A
they need genetic material
B
They need a host cell
C
They need bacteria
D
They need insulin
Explanation: 

Detailed explanation-1: -In the lytic cycle, the virus attaches to the host cell and injects its DNA. Using the host’s cellular metabolism, the viral DNA begins to replicate and form proteins. Then fully formed viruses assemble. These viruses break, or lyse, the cell and spread to other cells to continue the cycle.

Detailed explanation-2: -They are parasitic in nature and require the host to provide energy and replicate. Virus particles hijack the host cell and produce molecules required for viral reproduction. When they are independent, they are considered non-living and reproduce only by infecting host cells.
