In what cycle do temperate viruses reproduce?
How do viruses create new particles or organisms?
Viruses attach to cells of a host (humans, other living organisms). This is how they reproduce and cannot live without a host. They either go into a lytic cycle where they just keep reproducing by using the cell of the host (it is kind of like hacking, and making the cell work for them). viruses can also go into lysogenic cycle where they just stay in the cell undetected until they decide they want to…
Can viruses can reproduce outside a host cell?
What we need to understand is, viruses do not have its own synthetic machinery such as ribosomes to make proteins. Hence they are completely dependent on the host synthetic machinery for their replication. Virus infects the host cells, integrate its genetic material with the host to produce progeny viral particles.
How do viruses reproduce compared to bacteria?
Viruses replicate inside body cells, using the host cell to do the work and provide the materials for reproduction. Bacteria reproduce outside body cells and, since, unlike viruses, they are living organisms, bacteria are able to do the work and production of new bacteria without a need for a host. A description of the 'Lytic Cycle', the process that some types of viruses follow in reproduction, is given in the related questions below for more…
Where do viruses that cause colds reproduce?
Inside the cells of the host. Viruses can't reproduce without a host's body to do the work and provide the materials for replication. Most cold viruses first attack the mucous tissues, attach to and enter these cells and then force the cell to stop doing its usual job and begin slaving for the virus. The process is called the Lytic cycle, see the related questions below for more information.
How are germs created?
Three types of germs are there: Bacteria are single celled organisms, and they reproduce asexually. parasites are little animals and they reproduce sexually Viruses aren't technically alive. They invade a cell, take over it's DNA and force the cell to produce more viruses. Eventually the cell bursts releasing the versus and the cycle restarts
What true statements can you give about biological viruses?
True statements about biological viruses include that viruses: need a host to reproduce hijacks the body's cells to support the virus are easily transferable to others have no known cures most are self-limiting (end within 10-21 days), but some (AIDS, HIV) become lifelong illnesses sickens the host through proteins the virus produces weakens the immune system, making it easier to catch other infections have killed billions worldwide throughout history, especially the flu which led to…
How does the lytic cycle show that viruses are not living things?
The lytic cycle involves the viruses injecting nucleic acid into the cell to make the cell "sick". The lytic cycle proves viruses are non-living because the only way the cells reproduced at the end of the cycle was because of the host cell. A virus cannot reproduce on its own (only can with a host cell) as to which any living thing could. Viruses are non-living organisms and the lytic cylce proves just that. Viruses…
Why do viruses need a living host?
Viruses aren't even considered living entities. They do not have a means to reproduce on their own, so they need living cells to reproduce. Viruses alter the cell's "blueprint" and the cell begins to make more viruses. When the host dies, the cells die, and the virus cannot reproduce. Eventually it just breaks down.
Do viruses replicate by binary fission?
No, viruses reproduce in one of two different ways, they Lytic cycle and lysogenic cycle, Both cycles start the same way, the virus must get its nucleic acid (DNA or RNA but never both) into the cell. no the difference starts when the nucleic acid reaches the nucleus. In the lytic cycle (the more commonly used one) the virus uses the cell's ribosomes to code the viral nucleic acid and produce more viruses, the viruses…
What features do viruses and cells have in common?
Answer They do reproduce but a virus can't reproduce outside of a host cell so the only thing in common really is that the virus needs a cell to reproduce The only real similarity between viruses and living cells are that they both have some sort of genetic material. Cells have DNA and viruses have either RNA or DNA. But since viruses cannot reproduce on their own (because they are non-living) they need to reproduce…
Does bacteria kill viruses?
No. It's the other way around. Certain types of viruses (bacteriophage) will target bacteria, and they use the bacteria to reproduce the virus, called the Lytic cycle: The virus DNA or RNA enters the bacteria, takes over and new viruses are produced and when they break out of the cell through the membrane they destroy the bacteria in the process.
Do viruses need to be inside a living cell in order to reproduce?
Yes, viruses need a living host to replicate. A virion needs to be inside a living cell in order to "hijack" that cell so that more virus particles can be made by the cell. Since a virus is not a living thing, it doesn't reproduce in the same way that living cells reproduce. For more detail about the Lytic cycle in the viral replication process, there is additional information in the answers to the questions…
Compare and contrast bacteria and viruses?
Viruses are considerably smaller then bacteria. Instead of being a living cell able to undergo a life cycle on their own (bacteria can do this), they must take over the cell processes of another cell in order to reproduce. Viruses and bacteria are similar in that they both need a suitable environment to survive. Bacteria and viruses are both pathogenic (disease causing) to humans. Bacteria are killed by antibiotics. While viruses are not.
