Viruses and animal cells share a few common features, the most notable of which is the presence of nucleic acids. Both viruses and animal cells contain genetic material, either DNA or RNA, which is essential for their replication and functioning.
In addition to nucleic acids, both viruses and animal cells may have proteins; viruses have protein coats (capsids) that protect their genetic material, and animal cells contain various proteins that play critical roles in cellular functions. Moreover, both can be involved in processes that involve the exchange of genetic information, such as horizontal gene transfer in some contexts.
However, it is important to note that viruses are not considered living organisms and lack cellular structures and metabolic processes that are characteristic of animal cells.
