Which of the following is a similarity between viruses of bacteria (bacteriophages) and viruses of algae?     These viruses will enter host cells by membrane fusion.     They infect host cells by injecting nucleic acid (i.e., capsid does not enter cell)     After replication in a host cell, the newly-assembled viruses will exit the cell by budding.     These viruses are taken into host cells by phagocytosis.

Virus

Viruses are infectious microscopic agents that can only reproduce in live cells of animals, plants, or microbes and are smaller than bacteria. Vertebrates, invertebrates, plants, protists, and fungi are among their many hosts. Viruses are unable to multiply on their own due to the lack of necessary cellular machinery, but they can guide the cell machinery of a host to make additional viruses by infection. The virus enters and attaches to a particular host cell, injects its genetic material, and reproduces by using the host’s genetic material. Viruses cause infection by taking entry into the host cell and using the host cell’s enzymes and raw materials to multiply.
