Biological Evolution and Genetic Variation - ThoughtCo

WebKey points: Viruses undergo evolution and natural selection, just like cell-based life, and most of them evolve rapidly. When two viruses infect a cell at the same time, they may swap genetic material to make new, "mixed" viruses with unique properties. For example, flu strains can arise this way. WebBiochemistry or biological chemistry is the study of chemical processes within and relating to living organisms.
