Study Notes
Virus Characteristics
- Viruses are microscopic organisms only visible under an electron microscope
- They lack key cellular features including a nucleus, cytoplasm, mitochondria, or ribosomes
- Viruses possess an internal core containing either DNA or RNA, but not both
- Surrounding the core is a protective protein coat
- Some viruses may have an outer lipoprotein membrane, called an envelope
Viral Reproduction
- Viruses cannot generate energy or synthesize proteins independently
- They are obligate intracellular parasites, meaning they require host cells for replication
- Viral reproduction occurs within host cells and does not involve binary fission or mitosis
- One virus can replicate to produce hundreds of progeny viruses, while one cell only divides to produce two daughter cells
