Shapes & Structures
These are two parts to all viruses.
nucleic acid (DNA or RNA) and protein coat (capsid)
When a virus infects a bacterium, the virus injects this into the cell
Viral DNA or nucleic acid
One of the top reasons medicines cannot stop spread of disease is due to this.
they can't stop viruses from attaching to cells
This is how bacteria is different from viruses.
bacteria are alive
This is where nucleic acid is stored within a bacteriophage.
The head of the bacteria
If a person has HIV, but does not show the symptoms, then the virus is in this stage.
Lysogenic Cycle
This is a virus that does not have an available vaccine and easy to catch
the common cold
This is how vaccines are created.
virus from the material that causes the disease are injected into the organism
What shape was influenza A in your pamphlets?
Spherical or circle
This cycle destroys the host cell immediately
Lytic cycle
These are two ways viruses are similar to cells.
They have proteins, and nucleic acid (DNA or RNA)
TMV has this shape of?
Helical like DNA
During the lysogenetic cycle, the provirus does this.
inserts itself into cell and attaches itself to the DNA of the host and then is replicated
This is the type of cells that HIV targets?
White blood cells
what are the 5 steps in the lytic cycle
attachment, penetration or entry, replication, assembly, and release
What part of the bacteriophage injects the DNA in to cell
Spikes or small tail fibers
This is the most common threat to a host organism posed by an invading virus.
The destruction or lysing of the cell
Name all 7 steps of the lysogenic cycle
Attachment, Integration, lysogenic replication, Induction, lytic replication, assembly, and release
What is the Penetration step in the lytic cycle
When the viral DNA enters or penetrates the bacteria cell
