NEET BIOLOGY

Detailed explanation-1: -Viruses cannot replicate on their own, but rather depend on their host cell’s protein synthesis pathways to reproduce. This typically occurs by the virus inserting its genetic material in host cells, co-opting the proteins to create viral replicates, until the cell bursts from the high volume of new viral particles.

Detailed explanation-2: -A virus cannot replicate alone; instead, it must infect cells and use components of the host cell to make copies of itself. Often, a virus ends up killing the host cell in the process, causing damage to the host organism. Well-known examples of viruses causing human disease include AIDS, COVID-19, measles and smallpox.

Detailed explanation-3: -Viruses reproduce by infecting their host cells and reprogramming them to become virus-making “factories."

Detailed explanation-4: -Newly released virions can infect adjacent cells. A lysogenic cycle kills the host cell is not true statement of Viral replication.

Detailed explanation-5: -In a lytic cycle, the virus introduces its genome into a host cell and initiates replication by hijacking the host’s cellular machinery to make new copies of the virus.
