Influenza viruses, which cause seasonal flu and pandemics, are classic RNA viruses notorious for their rapid mutation and ability to evade vaccines. Examples of DNA Viruses DNA viruses are responsible for a wide array of diseases in humans, animals, and plants.
Designing Vaccines Targeting RNA and DNA Viruses
This evolutionary pressure is why we see frequent shifts in influenza strains requiring updated vaccines, whereas vaccines for DNA-based diseases like smallpox (now eradicated) and HPV remain effective for long periods. Other notorious RNA viruses include HIV, which attacks the immune system, and the hepatitis C virus, which targets the liver.
These viruses typically replicate inside the nucleus of the host cell, utilizing the host's own DNA machinery to transcribe and replicate their genetic code. Due to their error-prone replication process, RNA viruses often evolve quickly, making them challenging targets for long-term treatments and vaccines.
Designing Vaccines Against RNA Viruses: Challenges and Strategies
DNA viruses generally rely on the host cell's nucleus and its polymerases to transcribe their genes into messenger RNA, which is then translated into viral proteins. The Impact on Mutation and Evolution The chemical instability of RNA makes it more susceptible to mutations during replication.
