Some viruses have a capsid with proteins that act as "docking stations" so that they can attach to host cells. Others without capsids also have a different type of protein that does the same thing.

During viral protein synthesis what type of genetic molecule is used?
Messenger RNA
RNA is synthesized from viral DNA in an infected cell before protein synthesis begins?
true
What is the mode of action of nucleoside and nucleotide analogs?
Nucleoside and nucleotide analogs inhibit viral replication by incorporating into the viral genome during replication. These analogs lack the necessary functional groups for further elongation of the viral genome, leading to termination of viral replication and inhibition of viral protein synthesis. This disruption ultimately stops the virus from spreading and replicating.
What is a protein released by macrophages and activated T cells that helps to protect other body cells from viral multiplication?
Interferons
Why are helper t-cells required in an immune attack?
Helper T cell helps to develop anti viral protein interleukin
What is anti -viral protein?
Interleukin
What makes a viral capsid?
Protein of course :P
Where do viral particles get the materials for the protein - and nucleic acid - synthesis that they need to perform?
To carry out their Viral processes they 'utilize' the resources of The Host Cell.
When DNA from a virus is injected into a bacterium the bacterium produces viral protein?
blaze
Why do viruses depend in host cells?
Viruses are composed of protein and DNA. The DNA encodes the protein as well as the DNA for the virus. Viruses depend on host cells because they are incapable of reproducing themselves. They enter the host cell and the viral DNA is inserted into the host DNA. The virus then "hijacks" the host cells replication machinery to make more viral protein and viral DNA.
During viral protein synthesis what type of genetic molecule is used?
Messenger RNA
What protein helps to protect the body against viral infections is?
histamine is actually the wrong answer! it is interferons (which are proteins) and they are called that because they "interfere" with the virus.
RNA is synthesized from viral DNA in an infected cell before protein synthesis begins?
true
Which substances cause noninfected cells to form an antiviral protein that slows or stops viral multiplication?
Interferon
What happens to the viral protein coat after the virus has infected a cell?
It is shed like any overcoat and recycled.
