Howdy fellow user!
The envelope of a virus is made of a lipid bilayer derived from the host during the budding stage, basically the exiting stage of a newly made virus particle.
Let's do a little rewind.
The virus infects the cell to make many copies of itself by using the transcription and translational machinery available there. The virus proteins are translated first. Some of them are envelope proteins that get collected on the surface of the cell in a designated spot so when the virus buds off, it takes the bilayer with the accumulated envelope proteins.
Hope you found this response useful! 😄
What else can I help you with?
What action do viruses take when they enter the body' cell?
Viruses enter the body's cell and hijack the cell's machinery to replicate themselves. They use the cell's resources to make copies of their own genetic material and viral proteins, eventually leading to the destruction of the host cell as new viruses are released.
Why are Viruses not considered living by most Biologist?
Viruses are not an organism at all. They are not alive. They are nonliving. They are like cockle burrs that "grab" hold of your clothing or a dog's coat. They are hijackers. Once they get attached to the cell of a living cell, they can take it over and "make" the living cell produce virus particles instead of cell parts. These particles can assemble into more viruses and then they break out of the cell (killing it) and begin the process again. They cannot make more viruses on their own.
What does a virus do to its host cell?
A virus hijacks the host cell's machinery to replicate itself, causing the cell to produce more viruses. This can eventually lead to cell death and the spread of the virus to other cells.
What are oncogenes and how do they affect the cell cycle?
The region of the viral genome (DNA in DNA tumor-viruses or RNA in RNA-tumor viruses) that can cause a tumor is called an oncogene. This foreign gene can be carried into a cell by the virus and cause the host cell to take on new properties such as immortalization and anchorage-independent growth.
What does the ribosomes do to help the animal cell?
this is not an animal cell it is a biographice get your facts right
Do all viruses have an envelope?
No. I don't think so.
What is uses energy to take particles into a cell?
viruses
What surrounds a virus?
I take it that you meant to ask what surrounds the genome of the virus. The genome of the virus (be it DNA or RNA) is enclosed within the capsid shell. The capsid shell is made by the oligomerisation of capsid proteins in a specific organised manner. The genome together with the capsid is termed as nucleocapsid. Sometimes the nucleocapsid is surrounded by a phospholipid membrane (of host origin) called the envelope. The viruses which have an envelope are called envelope viruses eg., Chikunguyna virus, Rabies virus, HIV and the viruses without an envelope are called naked viruses eg., Poliovirus, Rotavirus
What do Golgi complex do in an animal cell?
they take the poos for the cell.
Do Viruses multiply through binary fission?
No, they do not. They are hijackers. Once they get attached to the cell of a living cell, they can take it over and "make" the living cell produce virus particles instead of cell parts. These particles can assemble into more viruses and then they break out of the cell (killing it) and begin the process again.No, only living cells divide by binary fission. Viruses are not alive.
What are Viruses that immediately take over a cell's functions called?
A virus the immediately takes over a cell's functions is an active virus. An active virus causes the host cell to make new viruses, destroying the host cell.
How does a virus different from a living cell?
viruses do not grow, take in food, or make waste living cell make waste, take in food, grow
What is the life cycle of a virus called?
A virus is RNA and DNA surrounded by protein. A virus can not live alone without a host cell. The life cycles are: attachment, penetration, uncoating, replication and release. During the release process, viruses may escape from the host cell by causing cell rupture viruses typically "bud" from the host cell. During the budding process, a virus acquires the phospholipid envelope containing the embedded viral glycoproteins.
What action do viruses take when they enter the body' cell?
Viruses enter the body's cell and hijack the cell's machinery to replicate themselves. They use the cell's resources to make copies of their own genetic material and viral proteins, eventually leading to the destruction of the host cell as new viruses are released.
How do viruses infect eukaryotic cells?
In bacterial viruses, the protein coat remains outside the cell and only the viral genome is injected into the cell. In animal viruses, the virus attaches to specific receptors on the plasma membrane and the whole virus is taken in by endocytosis (pinocytosis or phagocytosis). The viral envelope (if present) is stripped off inside the cell, and the separation of the viral genome from the protein coat then takes place. Not all infections of animal host cells result in lysis of the cell (as in the lytic cycle of bacteriophages). In the case of enveloped animal viruses, the viruses are released by a budding process. The process is slow and the host cell may remain alive and continue to release viruses over a long period of time. In some cases the virus may become dormant (though remaining infectious) inside the host cell, appearing spontaneously at a later time. (Unlike temperate bacteriophages that integrate their DNA into the genome of the host cell as provirus, animal viruses do not usually integrate into the animal genome during the latent stage.) Finally, some animal viruses may cause transformation of host cells to the cancerous state.--Differences between bacteriophages and viruses that infect eukaryotic cells
Why is it not correct to call a virus a microbes?
Viruses are not an organism at all. They are not alive. They are nonliving. They are like cockle burrs that "grab" hold of your clothing or a dog’s coat. They are hijackers. Once they get attached to the cell of a living cell, they can take it over and "make" the living cell produce virus particles instead of cell parts. These particles can assemble into more viruses and then they break out of the cell (killing it) and begin the process again. They cannot make more viruses on their own.
What can viruses reprouduce?
Viruses don't actually reproduce by themselves. When they enter somebodies body, they take over a cell and sort of hack its system to make the cell produce copies of the virus and not itself. That is why you get sick.
