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.
What else can I help you with?
True or false viruses are smaller than bacterial cells?
True. Viruses are smaller than bacterial cells. Bacterial cells are living organisms and are much larger in size compared to viruses, which are non-living particles that require a host cell to replicate.
Which is the largest a plant cell an animal cell or a bacterial cell?
Plant cells are generally larger than animal cells, and both are significantly larger than bacterial cells. Plant cells have a rigid cell wall that provides structural support and allows them to grow larger than animal cells, which do not have cell walls. Bacterial cells are much smaller than both plant and animal cells.
Why most viruses that infect bacteria have tails whereas most viruses that infect animals and plants do not?
Bacterial viruses, or bacteriophages, often have tails to help them attach to specific receptors on the bacterial cell surface. Animal and plant viruses typically do not need tails because they enter host cells through different mechanisms, such as membrane fusion or endocytosis. The diversity of host organisms and cell types likely contributes to the variety of viral structures seen across different types of viruses.
Bacteriophages are viruses that attack and destroy?
Bacteria by injecting their genetic material into the bacterial cells, which causes the cells to produce more viruses until they burst, releasing new viruses to infect other bacteria. Bacteriophages are being researched as a potential alternative to antibiotics for treating bacterial infections.
The event that occurs in bacteriophage multiplication that does not occur in animal virus replication is?
The event that occurs in bacteriophage multiplication that does not occur in animal virus replication is the injection of only the viral nucleic acid into the host cell. Viruses that infect bacteria are specifically called bacteriophages.
How does a bacterial differ from a plant cell or animal cell?
it does not have a nucleaus
How does bacterial cells differ from plant or animal cells?
it does not have a nucleaus
How does a bacterial cell differ from a plant or animal cells?
it does not have a nucleaus
What are viruses that prevent bacteria?
Viruses that prevent bacterial infections are called as "bacteriophages".
True or false viruses are smaller than bacterial cells?
True. Viruses are smaller than bacterial cells. Bacterial cells are living organisms and are much larger in size compared to viruses, which are non-living particles that require a host cell to replicate.
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.
Which is the largest a plant cell an animal cell or a bacterial cell?
Plant cells are generally larger than animal cells, and both are significantly larger than bacterial cells. Plant cells have a rigid cell wall that provides structural support and allows them to grow larger than animal cells, which do not have cell walls. Bacterial cells are much smaller than both plant and animal cells.
Example for bacterial RNA viruses?
Flu and HIV
Are bacterial viruses with a polyhedral head attached to a helical tail?
No, bacterial viruses with a polyhedral head typically have a tail associated with the head structure. These viruses are known as bacteriophages. The tail plays a critical role in attaching to the host bacteria and injecting the viral genetic material into the bacterial cell for replication.
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.
