What part of the lysogenic cycle is like the lytic cycle?
They both eventually cause death to the host cell. The lysogenic pathway includes integration into the host cell DNA, replication during fission, and a period of dormancy. The lytic pathway proceeds rapidly. The virus attaches and penetrates the host; viral DNA directs synthesis and replication; new viral particles are assembled and cuse the host cell to lysis. The infectious particles are quickly released into the host.
What are the spikes and there function in a virus?
Spikes are proteins that are part of the viral capsid/envelope (depending on if the virus is a naked virus or not). It helps with attachment to the host cell. They are derived from their host cell's own proteins (but are not the same as their hosts), and can help in evading the host cell's defenses.
What happens to the provirus when the host cell reproduces?
When the cell reproduces, the provirus is copied as part of the chromosome. The virus chromosome is placed into the host cell's.
What part of virus allows it to attach to a cell?
The proteins in the capsid allow the virus to attach to the "docking stations" proteins of the host cell.
How does a latent virus reproduce?
1)A SPECIFIC virus attaches to the surface of a specific bacteria cell.hereditary material of the virus injects into the cell. 2)The viral hereditary material may become a part of the bacterial cell's chromosome. 3)The bacterial cell divides the virus is now part of two cells inseted of one 4)The virus become active. 5)New virus are made 6)The bacterial cell breaks open and releases the viruses, thereby destroying the host bacterial cell.
What advantage does a virus have when invading an organism if it incorporates part of a host cell membrane into its envelope?
Envelopes aid the virus in entering the host's cells. Glycoproteins on the envelope's surface are unique to the virus. They identify and bind to receptor sites on the host's cell membrane.
What energy does the flu virus use?
It uses the energy of a host cell, in a sort of parasitic way. A virus is non-living, although it is a well structured organism able to reproduce and cause things to happen. To do these things, it does not generate or use its own power or energy. Instead, it invades a living host (a plant, animal or human) and attaches a virus particle into a cell and makes that living cell of the host to which it has attached change its operations from working for the host to working for the virus. The cell begins to create duplicates of the virus particles. It does this because once the virus has attached itself, it adds part of its own DNA or RNA instructions into the cell which turns the cell into a virus-making factory. The cell's original DNA is no longer giving the instructions to the cell and so it is no longer doing what it is supposed to for the host and eventually dies when it bursts open to release the virus "babies". This is what makes us get sick if enough of our cells are pulled off their usual jobs by the virus and made to do other things and then die. All the energy that is needed to reproduce the virus is supplied by the host cell, and as it produces new virus particles those "offspring" attach to more cells and the process repeats cell by cell particle by particle as it moves through our bodies and attaches to more cells. Eventually (hopefully) our body's immune system learns the key to turning the virus off (or "killing" it). If too many of our cells are diverted before the immune system figures out how to attack the virus to stop it, then we can have organ and system failures and that is how we get very ill or even die.
How is HIV different from other virus pathogens?
HIV is a retro virus, that infects your immune cells. The virus attaches to CD4 receptors on T-cell (the cells that are part of the immune system.)
What does a hidden virus do?
a hidden virus is were your virus is hidden so you have a virus but you can't see it. so its called a hidden virus.
How are the normal functions of the host cell affected by the provirus?
A virus can: 1. Kill the host cell 2. Alter the cell; incorporate into the genetic material of the host cell, thus becoming part of its nucleic acid pool; or divide when the host cell divides.
Which part of the virus takes over the host cell and contains the genetic material chooseCapsidDNAcytoplasmnone of the above?
DNA
Which part of the virus enters the bacteria and produced more viruses?
The virus attaches to the outer cell wall,inserts its DNA. It takes the cells functions over and starts a viral factory.
