What does the shape of the surface proteins allow the virus to do?
the shape of the surface protien allows it to attach "lock" itself on to certain cells in a host
What are the viruses protieins like?
like "keys" that fit only into certain "locks" or proteins, on the surface of a host's cells
Because the lock-and-key action of a virus is specific
a certain virus can attach only to one or a few types of cells
When can a virus attach itself to a cell?
only if the virus' surface proteins can fit those on the cell
Once a virus is inside a host cell what happens?
a virus's genetic material takes over many of the cell's funtions.
When a virus's genetic material takes over a cell's function what does it do?
It instructs the cell to produce the virus's proteins and genectic material.
What does the virus's genetic material do to the host cell?
it takes over the cells functions and starts to produce the virus's proteins and genectic material?
What does the invade cell start doing when the virus invades it?
it acts like a "photcopy machine" and makes copy after copy of the new virus
When the host cell if full of the new virus what happens to it?
the host cell bursts open releasing hundreds of new viruses and dies
After the Hidden Virus invades the host cell what does it do?
it become part of the host cell's genetic material
In a Hidden Virus what happens to it when the host cell divides?
the virus's genetic material is copies along with the host's genetic material
Where in a host cell does a hidden virus "hide" while it is inactive?
in the genetic material of the cell
What are the four way Viral Diseases can spread?
Contact with a contaminated object, bite of an infected animal, moisture droplets from sneezes and coughs, and contact with body fluids, like blood from an infected person
What are the three best things one must do to treat a viral infection?
bed rest, drink plenty of fluids, and eating a well-balanced meal
When you have a virus we can only do what?
treat the symptoms with over-the counter medications like advil
What is a Vaccine?
a substance introduced into the body to stimulate the production of chemicals that destroy specific disease-causing viruses and organisms
What are some ways to protect ourselves from getting a viral disease?
keeping a healthy body (rest, fluids, exercise), and by washing hands often and not sharing eating or drinking utensils
What role do the proteins in a virus's outer coat play in the invasion of a host cell?
it allows the virus to attach itself to the host cell like a key on the outer protein coat which locks onto the hosts cells surface protein cell
What are the additional steps that occur when a hidden virus multiplies?
it first hides in the genectic material and is copied when the cell divides and becomes unhidden when it is triggered to do so
