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

Anitbodies

Specialized proteins that aid in destroying infectious agents

Capsid

Surrounded by a

Capsid Definition

The outer protein coat

Four

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
