Which step is present in bacteriophage multiplication but not in multiplication of an animal virus?Multiple Choicea. New viral particles are released from the host cell by lysis.b. Viral genetic material is injected into the host cell.c. The viral genome is replicated by the host cell.d. Assembly of new viral particles occurs in the cytoplasm.e. New viruses exit the cell by budding from the cell membrane.
b. Viral genetic material is injected into the host cell.
The correct answer is (b) Viral genetic material is injected into the host cell.
Bacteriophages inject their genetic material into the host bacterial cell, while animal viruses typically enter the host cell through endocytosis or membrane fusion. The remaining steps of viral replication (viral genome replication, assembly, and release) are shared by both bacteriophages and animal viruses.
