Viruses cannot be killed by antibiotics..Why??

Antibiotics is a chemical that kills a particular cell, by blocking cell production. Viruses are not cells. This is why you can't get rid of a cold.



Viruses invade one cell which produce a strand of DNA then codes for the production of more viral RNA (retroviruses) producing new viruses and eventually killing the cell and organism. There are about 10 trillion cells in the human body.



So how do you cure a virus?



Viruses cannot be killed by antibiotics..Why??microsoft



Antibiotics can be both chemical and natural. they kill cells by blocking certain properties which lead to cell production such as penicillin which blocks formation of cell walls.



virus are different in that they are not cells but instead are parasites which cannot exist outside a cell. Virus inject their DNA into a cells and undergo a lytic or lysogenic cycle which leads to production of more viruses. This kills the cells. Also any cells which are detected by the virus are killed by our defense.



There is no cure to a virus however they can be treated or prevented. the most efficient way is vaccination in which weak strains of the virus is injected into a patient. this leads to the patient developing antibodies and memory cells which remember the virus and is much quicker in mounting an immune response when the actual virus is acquired. The is a flu vaccine however the flu virus is not stable and mutates to form new strains and hence the vaccine is not always effective.
