Final answer:
When infecting an animal cell, the virus follows similar stages as when infecting bacterial cells, including attachment, penetration, uncoating, replication, assembly, and release. However, the mechanisms of penetration, nucleic acid biosynthesis, and release differ between the two.
Animal viruses enter cells through endocytosis or membrane fusion, while bacteriophages inject their nucleic acid into bacterial cells.
Step-by-step explanation:
When infecting an animal cell, the virus goes through similar stages as when infecting bacterial cells: attachment, penetration, uncoating, replication, assembly, and release. However, there are some differences in the mechanisms of penetration, nucleic-acid biosynthesis, and release between bacterial and animal viruses.
Animal viruses enter cells through endocytosis or membrane fusion, and they may exhibit tissue tropism, meaning they only infect certain types of cells within tissues. In contrast, bacteriophages inject their nucleic acid into bacterial cells. Overall, the infection process for virus is similar in both animal and bacterial cells, but there are differences in how they enter and interact with the host cells.
