What occurs during viral uncoating?
During viral uncoating, the viral capsid is disassembled, releasing the viral genome into the host cell. This process allows the viral genome to access the host cell's machinery for replication and production of new virus particles.
What describes the number of virus particles circulating in an infected person?
Viral load is the term used to describe the number of virus particles circulating in an infected person. It is an important measure of virus replication and infectivity. Tracking viral load levels can help in monitoring disease progression and response to treatment.
Describe the last stage before escape in viral replication?
The last stage before escape in viral replication is packaging of the newly replicated viral genome into newly formed viral particles or virions. This process involves assembling the viral genome with viral structural proteins to form mature virions that can infect new host cells. Once the virions are fully formed, they are released from the host cell, allowing them to spread and infect other cells.
How does the virus make copies of itself?
Viruses make copies of themselves by hijacking host cells and using the cell's machinery to replicate their genetic material. The virus enters the host cell, releases its genetic material, and tricks the cell into making viral proteins and new viral particles. These new viral particles then go on to infect other cells and continue the cycle of replication.
What are the two ways viruses multiply?
Viruses can multiply either through the lytic cycle, where they infect a host cell and use its machinery to produce new viral particles that eventually burst out of the cell, or through the lysogenic cycle, where the viral DNA integrates into the host cell's DNA and replicates along with it until conditions trigger the virus to enter the lytic cycle.
What is the role of immune electron microscopy in viral diseases?
can be used to detect and identify viral particles that have too low concentration to be detected using conventional electron microscopy. binding of antibodies to the viral particles makes them easier to detect.
Describe the last stage before escape of a viral infection?
assembly of the virus particles and post-translational modification of the viral proteins.
What two processes are directed by viral genes that are activated inside the host cell?
Replication and assembly of new viral particles are processes directed by viral genes that are activated inside the host cell. The viral genes hijack the host cell machinery to produce more virus particles and assemble them before releasing them to infect other cells.
Where do viral particles get the materials for the protein - and nucleic acid - synthesis that they need to perform?
To carry out their Viral processes they 'utilize' the resources of The Host Cell.
What occurs during viral uncoating?
During viral uncoating, the viral capsid is disassembled, releasing the viral genome into the host cell. This process allows the viral genome to access the host cell's machinery for replication and production of new virus particles.
Would A virologist would likely be able to see viral particles with a light microscope?
No, viral particles are generally too small to be seen with a light microscope, which has a limited resolution of around 200 nanometers. Virologists typically use electron microscopes, which have much higher resolution, to observe and study viral particles.
What describes the number of virus particles circulating in an infected person?
Viral load is the term used to describe the number of virus particles circulating in an infected person. It is an important measure of virus replication and infectivity. Tracking viral load levels can help in monitoring disease progression and response to treatment.
The number of virus particles circulating in an infected person's body is called what?
Viral load
What is the term used when a host cell is actively making viral particles?
The term for a host cell actively making viral particles is "viral replication." During this process, the virus takes over the host cell's machinery to produce new viral components, which eventually assemble into complete viruses that can infect other cells.
Describe the last stage before escape in viral replication?
The last stage before escape in viral replication is packaging of the newly replicated viral genome into newly formed viral particles or virions. This process involves assembling the viral genome with viral structural proteins to form mature virions that can infect new host cells. Once the virions are fully formed, they are released from the host cell, allowing them to spread and infect other cells.
What does the term maturation refer to in the lytic cycle?
c. assembly of parts to produce viral particles
What is a solution made from weakened virus particles that prevents viral disease?
vaccine
