WebFor instance, viruses—tiny protein and nucleic acid structures that can only reproduce inside host cells—have many of the properties of life. However, they do not have a cellular structure, nor can they reproduce without a host. Similarly, it’s not clear that they maintain homeostasis, and they don’t carry out their own metabolism.

WebThe short answer to these questions is that viruses evolve.That is, the "gene pool" of a virus population can change over time. In some cases, the viruses in a population—such as all the flu viruses in a geographical region, or all the different HIV particles in a patient's body—may evolve by natural selection.Heritable traits that help a virus reproduce (such as high … WebAnimal viruses do not always express their genes using the normal flow of genetic information—from DNA to RNA to protein. Some viruses have a dsDNA genome like cellular organisms and can follow the normal flow. However, others may have ssDNA, dsRNA, or ssRNA genomes.
