Does viral replication only occur in mitosis?
No, viral replication can occur in both mitotic and non-mitotic cells. Viruses can hijack the cellular machinery of the host cell to replicate their own genetic material and produce new virus particles regardless of whether the host cell is actively undergoing mitosis.
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.
What injects DNA and RNA into nucleus of the cell to reproduce?
Viruses inject their genetic material (DNA or RNA) into the host cell's nucleus in order to replicate. Once inside, the viral genetic material hijacks the cell's machinery to produce more viral particles.
What makes copies of viral DNA?
During the process of viral replication, the virus uses host cells to produce copies of its viral DNA. This process typically involves the virus injecting its genetic material into the host cell's nucleus, where it hijacks the cell's machinery to replicate its DNA. This results in the production of multiple copies of the viral DNA, which can then be packaged into new viral particles.
What are the steps of HIV replication in the correct order?
Attachment: HIV binds to the CD4 receptor on the host cell. Fusion: The viral membrane fuses with the host cell membrane. Reverse transcription: Viral RNA is reverse-transcribed into DNA by reverse transcriptase. Integration: The viral DNA is integrated into the host cell's genome. Transcription and translation: Viral genes are transcribed and translated to produce new viral proteins. Assembly: New viral particles are assembled. Budding: Mature HIV particles bud off from the host cell.
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.
Does viral replication only occur in mitosis?
No, viral replication can occur in both mitotic and non-mitotic cells. Viruses can hijack the cellular machinery of the host cell to replicate their own genetic material and produce new virus particles regardless of whether the host cell is actively undergoing mitosis.

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.
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 events stimulates the production of viral particles in a host cell?
Activation of the host cell by cytokines, growth factors, or antigens
Viral RNA uses the normal process of a cell to manufacture?
Viral RNA hijacks the host cell's machinery to replicate and produce viral proteins. It uses the cell's resources and machinery, such as ribosomes and enzymes, to make copies of itself and assemble new viral particles. This process can ultimately lead to the destruction of the host cell.
What process is used by some protists to actively ingest food particles?
Some protists use a process called phagocytosis to actively ingest food particles. During phagocytosis, the protist surrounds the food particle with its cell membrane and forms a vesicle, called a food vacuole, to bring the food particle into the cell for digestion.
What injects DNA and RNA into nucleus of the cell to reproduce?
Viruses inject their genetic material (DNA or RNA) into the host cell's nucleus in order to replicate. Once inside, the viral genetic material hijacks the cell's machinery to produce more viral particles.

What viral infection that leads to the integration of the viral genome into the host cell genome?
HIV (Human Immunodeficiency Virus) is a viral infection that leads to the integration of the viral genome into the host cell genome. This integration allows the virus to replicate along with the host cell's DNA, making it difficult for the immune system to eradicate the virus completely.
What are the steps of HIV replication in the correct order?
Attachment: HIV binds to the CD4 receptor on the host cell. Fusion: The viral membrane fuses with the host cell membrane. Reverse transcription: Viral RNA is reverse-transcribed into DNA by reverse transcriptase. Integration: The viral DNA is integrated into the host cell's genome.
