10 Questions
What are the four categories of viruses based on the type of nucleic acid they possess?
Double-stranded DNA viruses, Single-stranded RNA viruses, Single-stranded DNA viruses, Double-stranded RNA viruses
Describe the steps in the multiplication of animal viruses.
Attachment, Penetration, Uncoating, Biosynthesis, Assembly
What is a latent virus infection?
Viral infections where the virus hides from the immune system by remaining dormant
What are oncogenic viruses?
Viruses that cause cancer
What are the primary targets for the Human Immunodeficiency Virus (HIV)?
CD4+ cells with CD4 receptors on their surface
What distinguishes viruses from living cells in terms of DNA and RNA?
Viruses possess either DNA or RNA, while living cells possess both.
Describe the structure of a typical virion.
A typical virion consists of a genome of either DNA or RNA, surrounded by a capsid (protein coat) composed of capsomeres. Some may have an outer envelope of lipids and polysaccharides.
What is the role of host cells in viral replication?
Viruses depend on the ribosomes, enzymes, and metabolites of the host cell for protein and nucleic acid production.
Explain the term 'oncogenic viruses' or 'oncoviruses'.
Oncogenic viruses are viruses that cause specific types of cancer.
Why are viruses considered acellular microbes?
Viruses lack the ability to replicate on their own and require a host cell for replication.
Learn about the categorization of microbes into cellular (bacteria, archaea, algae, protozoa, fungi) and acellular (viruses, viroids, prions), as well as the distinction between prokaryotic (bacteria, archaea) and eukaryotic (algae, protozoa, fungi) microorganisms.
