1) The major difference between these two is that the RNA viruses have RNA in their genome while the DNA viruses have DNA in their genome. Both the DNA and RNA cannot be found in the same virus. RNA virus first adsorbs to the host cell surface. Then the attached virus fuses with the endosome membrane. Unlike RNA viruses, DNA viruses pass their DNA into the nucleus of the host cell and not into the cytoplasm of the host cell.
2) Lysis: refers to the breaking down of the membrane of a cell, often by viral, enzyme, or osmotic mechanisms that compromise its integrity. A fluid containing the contents of lysed cells is called a lysate.
Lysogenic: the biological process in which a bacterium is infected by a bacteriophage that integrates its DNA into that of the host such that the host is not destroyed.
Virulence: the degree of …show more content…
Because the germ has been killed or weakened before it is used to make the vaccine, it cannot make the person sick. When a person receives a vaccine, the body reacts by making protective substances called "antibodies". The antibodies are the body's defenders because they help to kill off the germs that enter the body.
5) When a virus infects a person (host), it invades the cells of its host in order to survive and replicate. Once inside, the cells of the immune system cannot ‘see’ the virus and therefore do not know that the host cell is infected. To overcome this, cells employ a system that allows them to show other cells what is inside them. A special cell of the immune system called a T cell circulates looking for infections. One type of T cell is called a cytotoxic T cell because it kills cells that are infected with viruses.
6) It was important because this taught the world health organization how to treat wide spread disease. They practiced and trained the members of WHO how to treat large amounts of people in a short period of
