Viruses are composed of two main parts an outer protein covering called a capsid and an inside core of either DNA or RNA. Not both DNA and RNA. Some of these have an envelope over the capsid. The ones that do not are said to be naked. The proteins in the capsid allow the virus to attach to the "docking stations" proteins of the host cell. The naked viruses are more resistant to changes in the environment.

Why does hep a targets liver cells?
All of these viruses like Hep A, B or C have matching proteins that work like a docking stations. They have one that fits just so with the one on the liver cell. Other viruses work the same way. The influenza virus affects the cells of the respiratory tract. Chickenpox viruses affect the skin but also the nerves.
What are the Proteins released from plasma cells to fight infection called?
The proteins released from plasma cells to fight infection are called antibodies. Antibodies are specific proteins that identify and neutralize pathogens, such as bacteria or viruses, helping the immune system to eliminate the infection.
What particles reproduce that are made up of nucleic acids proteins and sometimes lipids only infecting living cells?
Viruses are particles that reproduce by infecting living cells. They consist of nucleic acids, proteins, and sometimes lipids.
Are viruses general or specific to the cells that they infect?
viruses are specific to the cells they infect called host cells
Proteins on the outside of the aids virus bind to what?
proteins on the surface of red blood cells
Why are most viruses highly specific to cells they infects?
viruses must bind precisely to proteins on the cell surface and than use a hosts genetic system, this is why most viruses are highly specific to the cells they infect
What are in viruses?
They don't belong to a kingdom because they are not cells. They are just genetic material wrapped in proteins that reproduce inside of cells.
What are spikes on viruses made of?
Spikes on viruses are made up of proteins that are used to attach the virus to host cells. These proteins play a critical role in allowing the virus to enter and infect host cells by binding to specific receptors on the cell membrane.
Are interferon's viruses?
Interferons are not viruses. They are a group of signaling proteins released by cells in response to the presence of pathogens like viruses. Interferons help to regulate the immune response and inhibit viral replication within infected cells.
What are 2 non-living pathogens?
Viruses and prions are examples of non-living pathogens. Viruses require host cells to replicate, while prions are misfolded proteins that can cause disease by inducing other proteins to misfold.
What is the medical term meaning proteins foreign to the body?
A heterologous protein; however, any abnormal substance (bacteria, viruses, cancer cells) in the body is called an antigen
Proteins that destroy substances that are not part of your body are called what?
Proteins that destroy substances that are not part of your body are called antibodies. Antibodies are produced by the immune system to help protect the body against harmful invaders like bacteria and viruses.
