The lytic cycle causes destruction of infected cells and their membrane. A virus that uses a lytic cycle reproduces itself or makes copies that are sent back into the environment and they are called virulent viruses.
The pox virus is related to the herpes viruses and they are lytic but can become latent. Latency is not the same as lysogenic.
They are upper respiratory infections caused by viruses. Viruses are non-living organisms that use the lytic and lysogenic cycles to reproduce. See the related question below for more information about the lytic cycle which is the process of viral replication.
Actually viruses don't reproduce, but "replicate". It's sort of a cloning process. They use either the process of the Lytic Cycle for replication or they use replication without lysis with a process known as "Budding".
it infects cells by injecting its dna into them. the cells then use their resources to make new viruses. the cell wall eventually lyses, exposing the viruses to new cells for infection. thats the lytic cycle. the lysogenic cycle is next. the lysogenic cycle has the same start. however, the cell reproduces on its own, replicating the dna of the virus. and the lytic cycle could go off at any time, causing mayhem. MAYHEM.
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.
Viruses can be grouped by their shape, the type of disease they cause, their life cycle, or the kind of genetic material they contain. And, the four main shapes of viruses are: Crystals, Spheres, Cylinders, and Spacecraft.
The Lytic Cycle describes the process. This is the mechanism by which viruses infect a host, take over the function of the cells, and use them to replicate millions of new viruses in your body. The word lytic is used since the infected host cells are lysed (split open), and killed in the process, as the new virus particles mature and are ready for release in the body. Common cold viruses infect the cells of the mucous tissue in humans, mostly that of the respiratory system. However, cold viruses also infect the tissues in the eyes, mouth and the rest of the gastrointestinal system with mucous tissue.
The lytic cycle is one of two methods of viral reproduction, the other being the lysogenic cycle. These cycles should not, however, be seen as separate, but rather as somewhat interchangeable. The lytic cycle is typically considered the main method of viral replication (reproduction), since it results in the destruction of the infected cell.The lytic cycle is often described in steps, sometimes three steps, sometimes five steps or six steps. But all describe the same process. See the related question below for more information about the steps of the lytic cycle.Penetration To infect a cell, a virus must first enter the cell through the plasma membrane and (if present) the cell wall. Viruses do so by either attaching to a receptor on the cell's surface or by simple mechanical force. The virus then releases its genetic material (either single- or double-stranded DNA or RNA) into the cell. In doing, the cell is infected and can also be targeted by the immune system.Biosynthesis The virus' nucleic acid uses the host cell's machinery to make large amounts of viral components. In the case of DNA viruses, the DNA transcribes itself into messenger RNA (mRNA) molecules that are then used to direct the cell's ribosomes. One of the first polypeptides to be translated is one that destroys the hosts' DNA. In retroviruses (which inject an RNA strand), a unique enzyme called reverse transcriptase transcribes the viral RNA into DNA, which is then transcribed again into mRNA.Maturation and lysis After many copies of viral components are made, they are assembled into complete viruses. The phage then directs production of an enzyme that breaks down the bacteria cell wall and allows fluid to enter. The cell eventually becomes filled with viruses (typically 100-200) and liquid, and bursts, or lyses; thus giving the lytic cycle its name. The new viruses are then free to infect other cells.Lytic cycle without lysis Some viruses escape the host cell without bursting the cell membrane, but rather bud off from it by taking a portion of the membrane with them. Because it otherwise is characteristic of the lytic cycle in other steps, it still belongs to this category. Hepatitis C viruses presumably use this method.
Injection. After the virus has attached to the cell wall, it then injects its genetic material into the cell.
Since viruses are not actually living things (because they do not grow, do not have homeostasis, and do not metabolize) I don't think they produce like anything else (neither sexually nor asexually). They reproduce by first infecting a living cell. They rely on host cells to reproduce because they lack the enzymes necessary for metabolism and have no structures to make protein. Then, the bacterial virus (bacteriophage) punches a hole in the cell wall and injects its DNA into the cell. Or, a plant virus enters a plant cell through tiny rips in the cell wall at points of injury. Animal viruses enter host cells through endocytosis. Then, viruses either go through the lytic or lysogenic cycle. In the lytic cycle, the virus attaches to a cell and injects it own bacterial DNA. Then the viral genes control the host cell and force it to replicate viral genes and to make viral proteins, such as caspids. The proteins are then combined with new copies of DNA, to make new complete viruses. Then, the host cell breaks open and releases the new viruses. During the lysogenic cycle, the viral DNA is replicated and embedded into the bacterial DNA so it copies, but doesn't destroy the host cell. Symptoms may not appear for a long time. Then, something triggers the virus and it goes through the lytic cycle. Most of this information (some of it word for word) came from my biology textbook, "Biology: Principles and Explorations" by Holt, Rinehart, and Winston. Hope that was clear enough and that it helps!
The rock cycle is how one type of rock can be changed into another type of rock.
Lytic. Lysogenic viruses typically encode themselves into the cell's DNA (Example: HIV uses a viral-encoded reverse transcriptase to do so), Ebola typically bursts from the cells via apoptosis and/or pyroptosis. Lysogens typically reside in the cell for long periods of time, sometimes budding off virions. Lytic viruses typically use the cell's machinery to make as many virions as possible and burst the cell open in order to spread to more host cells.

yes medical viruses does use energy
Viruses use host cells to reproduce.
An electron microscope can be used to view viruses. Scientists can use a negative stain to view bacteria and different types viruses.
It is a 2 cycle engine and therefore you must use 2 cycle oil mixed at the correct ratio with the fuel.
The more the mass the shorter their life cycle (the more quickly they use their fuel)
"one type of rock can be changed into another type of rock"
Computers are typically protected from viruses by the use of firewalls.
To see viruses, an electron microscope would be your best bet.
So cell cycle is independent of nutritional state. Compare and contrast to the virus Lambda, which makes a molecular decision whether to be in the lytic or lysogenic cycle based on the number of proteases - linked to nutritional state (and hence nutritional state of the infected cell).
Through mutation of an existing virus into new forms. Usually, there is mutation of the protein coating of the virus that results in a new strain. The new strain may or may not be infectious to the same group or organism that was vulnerable to the original virus strain. For a case example of how new viruses form, see the related question below that explains in detail what caused the new 2009 Pandemic Swine Flu virus. Also see the related question about the Lytic Cycle, which is the process that viruses use to attach to cells and reproduce.
Sounds like a project question. Research it... and make sure you use a credible source.
Use a quality 2 cycle oil only. I recommend you use a synthetic 2 stroke oil.
Viruses are not living pathogens, they are "organisms" with the ability to duplicate themselves ~ but only if they have a living host to provide the energy and materials for the duplication process. Different viruses use different hosts and most of the time they don't cross over species for hosts, but some do. The H1N1/09 virus was able to mutate from a strain that pigs got to a strain more targeted toward people. Other viruses use plants and other animals for hosts.The short explanation of how this happens is:Virus is in the environmentHost is exposed to the virus in the environmentSome virus particles are able to attach to the cell walls of the cells of the host.The virus connects to the center of the cell and injects genetic material that the virus uses to instruct the host cell how to make virus duplicatesHost makes new virusesVirus duplicates get out of host cells and spread to infect more hostsSee the related questions below about the lytic cycle of viruses.
