well, viruses are microscopic particles that can infect the biological cells by replicate themselves in the infected host cell. Viruses contain only DNA or RNA %26 coat protein (capsid).



Viruses do not replicate during cell division because they are acellular (not living organisms they are only particles), so they use the host cell metabolism to multiply (control the host cell mechanism for its multiplication).



During the cell (host cell) division, viruses genetic information (DNA or RNA) interferes with the production of the DNA of the host cell (interfere with the replication of the host cell DNA) so that time, the host cell produce defected DNA thus this defected DNA transcripts defected m RNA and this defected RNA translates to dysfunction protein that cant act will in the cell so that causes a assortment of diseases.



I hope that my knowledge was useful for you. Good Luck

viruses, like other active organisms usually start out as friends... maybe they go out, have a few drinks, get to know each other. one day they kiss, maybe some fondling... eventually one thing will lead to another and they have sex. if the time is right (or sometimes not) they may have kids. reproduction rocks.
