Do viruses have DNA? Short fast 1 minute answer
Viruses are complex forms of life that we know as a pathogen for the target.
A virus is a small collection of genetic code, either DNA or RNA, surrounded by a protein coat. A virus cannot replicate alone. Viruses must infect cells and use components of the host cell to make copies of themselves. Often, they kill the host cell in the process, and cause damage to the host organism.
