Viral genetics refers to the study of the genetic material and processes involved in the replication, evolution, and transmission of viruses. Viruses are microscopic infectious agents that lack the cellular…
Viral evolution refers to the process by which viruses undergo changes in their genetic material over time, leading to the development of new strains and variants. Evolutionary processes in viruses…
Virus mutation and variation are essential aspects of viral biology that play a significant role in the adaptability, evolution, and diversity of viruses. Mutation Rates: Viruses exhibit different mutation rates…
