Study Notes
Viruses vs Bacteria
- Viruses are not considered living organisms, whereas bacteria are.
- The main difference between viruses and bacteria is that viruses are obligate intracellular parasites, meaning they need to infect a host cell to replicate, whereas bacteria are capable of reproducing independently.
Viral Reproduction
- Viruses reproduce by hijacking the host cell's machinery to produce new viral particles.
- The process involves the virus attaching to the host cell, releasing its genetic material, and then using the host cell's machinery to replicate and assemble new viral particles.
