Viral replication strategies ?

Question

Can anyone help me discuss the viral replication strategies to produce infection??

Answer 1

A virus is not a living organism, insted it is a piece of DNA which corrupts living cells. The virus implants its DNA into the nuclues of a living cell. The cell now has the virus's DNA which is designed to make the inital cell produce more viruses. This causes an exponential chain reaction.

Answer 3

It depends on the virus, some will use pieces of the cell they previously infected to create a membrane around themselves, this evades host-defenses since the host recognizes the antigen on the surface of the virus, the host has a hard time defending itself against the infection.

Some viruses also go from RNA to DNA using Reverse Transcriptase, which is a very highly error prone enzyme, and even the change of one base pair can completely alter how a virus "looks" in terms of antigens.  Viruses like HIV employ this strategy.  

Viruses are constantly "evolving" and I use that term loosely, since according to cell theory they are not living, to evade host defenses.  It's a constant battle between our immune system against them.

Hope this helps.
