The genomes of organisms are all composed of DNA, whereas viral genomes can be of DNA or RNA.

In fact, some mutations could make the virus less infectious. Much of our knowledge of how viruses change to escape natural or vaccine-elicited immunity comes from observing the influenza virus and constantly updating influenza vaccines. Influenza viruses change in two main ways, antigenic drift and antigenic shift.
2 days ago · Definition. A mutation is a change in the DNA sequence of an organism. Mutations can result from errors in DNA replication during cell division, exposure to mutagens or a viral infection. Germline mutations (that occur in eggs and sperm) can be passed on to offspring, while somatic mutations (that occur in body cells) are not passed on.
