retro virus = any of a family of single-stranded RNA viruses having a helical envelope and containing an enzyme that allows for a reversal of genetic transcription, from RNA to DNA rather than the usual DNA to RNA, the newly transcribed viral DNA being incorporated into the host cell's DNA strand for the production of new RNA retroviruses: the family includes the AIDS virus and certain oncogene-carrying viruses implicated in various cancers.

∙ 10y agoA retroviruses is different fom other animal viruses because it can transcribes mRNA into a host for formation od new DNA , where as a regular viruses transcribes DNA into RNA.

Which is the largest a plant cell an animal cell or a bacterial cell?
animal cell ____________________________________ viruses are not cells. but it would be the animal cell.
How do viruses and cellular organisms differ?
Viruses are not classified as living, while cellular organisms are. Viruses are essentially a protein case with mRNA inside. Cells are far more complicated.
Why plant animal and bacterial cells have different parts?
well, bacterial cells are mostly made to destroy and damage other cells and plant and animal cells are meant to produce and help the body.
Of what material is the envelope present in some animal viruses composed?
The envelope present in some animal viruses is composed of lipids. This lipid material is derived from the cell membrane of the host.
Microbiology If there were no plaques on your plate offer an explanation?
Because viruses cannot multiply without a host cell, they cannot be grown in sterile media the way bacteria can. Host cells must be provided for the virus to infect. Bacteriophage may be cultured with bacterial cells in liquid culture or on plates. To culture on plates, bacteria and bacteriophage are combined in melted agar and then poured into plates. The bacterial cells divide and evenly cover the surface of the plate forming a lawn. Wherever bacterial cells have been destroyed by the bacteriophage, clearings called plaques will appear in the lawn. Because it is harder to culture animal cells than it is for most bacteria, it is also more difficult to grow animal viruses in the lab. Some animal cells will grow in culture dishes much as bacteria do and will form a single layer on the bottom of a dish that contains a suitable growth medium. Viruses that can infect these cells can be grown along with them. Animal cells that are infected by the virus will display visible deterioration. Some viruses whose host cells can not be grown in culture can be grown in living animals such as rabbits, mice, and guinea pigs. Other viruses can be grown in fertilized chicken eggs. However, because some viral host ranges are highly specific, each virus infects only certain cell types, I cannot grow all cells in culture, yes grow all viruses.

What are viruses that prevent bacteria?
Viruses that prevent bacterial infections are called as "bacteriophages".
How does the immune response to viruses differ from the immune response to bacteria?
It happens as our body do not have anti-bodies [ means the copy of the virus to make a trap for it ], but in bacterial it is done just by destroying as the bacteria do not conquer a tissue or a cell to make their army.
What is true regarding bacteria and animal cells?
,The bacterial cell walls are similar in function to the cell wall s of the plants, fungi, and protists. The bacterial cell walls differ in the molecular composition from plant cell walls.
Example for bacterial RNA viruses?
Flu and HIV
How is the flu different from bacterial infections?
It is caused by viruses not by bacteria.
What is meant by bacterial diseases?
Bacterial diseases are diseases caused by bacteria, in contrast to those caused by parasites, viruses, or fungi.
Are bacterial viruses with a polyhedral head attached to a helical tail?
bacteriophages
What is the binding of antibodies to specific sites on bacterial exotoxins or viruses?
It is Neutralization
