Like cells, Viruses contain "nucleic acids".
<u>Answer:</u> Option C
<u>Explanation:</u>
Either DNA or RNA is contained in all viruses in the form of nucleic acid but not the both. Viruses encapsulates nucleic acid in a protein cover. Viruses are divided into four shape-based groups named as filamentous, isometric or icosahedral, enveloped, head and tail form.
Virus life cycle is comprised of basically attachment; penetration; uncoating; replication; assembly and finally release. Viruses can only spread by penetration of a host cell and can not replicate themselves. Viruses are a genetic material (not cells) inside a protective proteins coat called a capsid. They infect a large range of species including eukaryotes as well as prokaryotes.
