Answer:
a. genetic material
Step-by-step explanation:
Viruses (from the Latin “poison” or “toxin”) are obligatory parasites of living things. This is because they cannot multiply their genetic material if they are not inside an organism.
The virus approaches the cell and injects its genetic material. This material enters the cell and multiplies with the help of the infected cell organelles. Hence, the virus's DNA or RNA will characterize the type of infection and disease. The infected cell dies and releases the viruses that have formed inside it and these viruses will infect other cells. This process can also occur in another way, where the virus introduces its genetic material into the cell. This material will be part of the cell's DNA and will be replicated during the cell meiosis process.
Based on this, we can say that the virus reproduces using the host cell, which eventually generates genetic material for the virus.
