Characteristics of Viruses
These are two parts to all viruses.
What are the nucleic acid and protein coat (capsid)?
Host cell for this phage.
What is a bacterium?
Required for a virus to become active and reproduce.
What is a host cell?
I am used for culturing bacteria and other microbes but NOT viruses.
What is culture medium?
Small, circular pieces of RNA that cause plant disease.
What are viroids?
Lipid layer that surrounds some viruses made from the host cell membrane.
What is the envelope?
If a person has HIV, but does not show the symptoms, then the virus is in this stage.
What is lysogentic cycle?
Cell bursting due to newly formed viruses.
What is lysis?
I am living, immortal, and can divide indefinitely.
What are continuous cell cultures?
Protinaceous infectious agents that cause bovine spongiform encephalopathy ("mad cow disease") in cattle.
What are prions?
Nucleic acid found in Retroviruses.
What is RNA?
This cycle destroys the host cell.
What is the lytic cycle?
An enveloped virion is created by this release process.
What is budding?
I am composed of proteinaceous subunits called capsomeres and serve to protect.
What is a capsid?
Enzyme that converts retroviral ssRNA into dsDNA.
What is reverse transcriptase?
Projections made of protein and sugar chains on the surface of an envelope to aid in attachment.
What are glycoproteins?
Used to attach to their host cell.
What are tail fibers?
Mechanism of entry in which the cytoplasmic membrane of host engulfs virus.
What is endocytosis?
Air sac, yolk sac and embryo are some of my inoculation injection sites.
What are embryonated chicken eggs?
What is a nucleus and cytoplasm, respectively?
Virus exists as nucleic acid.
What is intracellular state?
The only part of the phage NOT made of protein.
What is nucleic acid?
Attachment, Entry, Synthesis, Assembly and Release.
What are the five stages of viral replication?
Hello! E. coli here. I've been attacked by a bacteriophage. Lysis of my cells produced these holes in my lawn called...
What are viral plaques?
Used to prevent many viral diseases.
What are vaccines?
