What is a key role of viruses in biogeochemical cycling?
Press to flip
Viruses help recycle organic matter, which is crucial for ecosystems.
How do viruses differ from cellular organisms in terms of reproduction?
Viruses do not reproduce by binary fission; they assemble within infected cells.
How have recent advances in genome sequencing impacted virology?
Recent studies have discovered thousands of new viruses through genome sequencing.
Why is the study of viruses crucial for comprehending life on Earth?
Viruses infect every living organism and play critical roles in ecosystems and biogeochemical cycles.
How do viruses contribute to human health besides causing diseases?
Many viruses are benign or contribute positively to our health without causing disease.
What impact do viruses have on human history?
The concept of viruses has evolved, influencing historical perceptions of infectious diseases.
Why is virology considered an integrative science?
Virology combines elements of biology, chemistry, sociology, and psychology to provide a comprehensive understanding of viral interactions and impacts.
Why are viruses considered obligate intracellular parasites?
They cannot reproduce outside host cells and need to infect a host cell to replicate.
What are some key characteristics that define viruses?
Viruses are infectious obligate intracellular parasites with DNA or RNA genomes, and they cannot reproduce outside host cells.
Why are viruses important for the understanding of ecosystems and biodiversity?
Viruses shape ecosystems, drive biogeochemical processes, and are involved in biodiversity.
What is the significance of giant viruses?
Their discovery expanded the understanding of viral size.
How does the immune system generally handle viral infections?
The immune system typically manages to keep viral infections under control, preventing diseases.
Besides causing respiratory diseases, how else have viruses contributed to major global causes of death?
Viruses are also involved in causing cardiovascular diseases and cancers worldwide.
Describe the process of viral infection in terms of immune system interaction.
The immune system typically keeps viral infections in check unless it is suppressed, which can allow reactivation of latent viral infections.
What historical figures were instrumental in the understanding of viruses as infectious agents?
Pasteur, Koch, and Chamberlain contributed significantly to the understanding of infectious agents.
