Viruses- Pre-Ap Biology
Non-Living
A Virus is a ________ Particle
Bacteriophages
A virus that infects bacteria
Vaccines
A weakened or inactive version of a pathogen that stimulates the body's production of antibodies which can aid in destroying the pathogen
Lytic Cycles
Active (ex: Cold virus)
Envelope Definition
It matches the membrane of the hosts
Lysogenic Cycles
Latent (Ex: HIV)
Must Recognize
Lock and Key
Host
Lock and Key between virus and _______
Release of Virus by
Lysis or Exocytosis
Two types of cycles
Lytic & Lysogenic
Inject
May ____ Its nucleic acid into host
Attachment to the Host cell
Must *Recognize* cell Viruses only with a *capsid* *Viruses* with *Envelope* *" Lock and Key"* between virus and host
Host; Replicate
Must have "_______ cell" to _______
Kingdom; DNA (or RNA); protein coat; size; type
Not part of any _____. Classified by genetic material,______, _______ _______, ______, _____ of host it infects.
Viruses with RNA
Once inside the host, the retrovirus make DNA from their RNA by an enzyme in their capsid in their capsid called: Reverse Transcriptase DNA is made and then integrated in the host, becoming a provirus (ex :HIV)
Transcriptase
Once inside the host, the retrovirus make DNA from their RNA by an enzyme in their capsid in their capsid called: Reverse _________
Vacuole
P.Membrane of host brings virus in as a ________
What can destroy a virus
Phagoatic Cells Lymph Nodes Anitbodies Vaccines
Lymph Nodes
Phagocytic cells located these
Virus with only a capsid
Protein membrane
The shape
Proteins in the capsid determine ______ ________
Envelopes
Some have ______ surrounding the capsid

Specialized proteins that aid in destroying infectious agents
Capsid
Surrounded by a
Capsid Definition
The outer protein coat

Viruses can be in _______ Shapes
Exocytosis
When the virus fuses with the P.Membrane of the host, it takes some of the p.membrane with it. which becomes the Envelope
