Which of these does a virus need in order to multiply?(1 point)
Responses
A host cell to provide oxygen for the virus
A host cell to provide oxygen for the virus
Chloroplasts from a host cell
Chloroplasts from a host cell
A host cell to replicate the virus’s DNA
A host cell to replicate the virus’s DNA
New ADP from a host cell
A host cell to replicate the virus’s DNA
A virus needs a host cell to replicate its DNA.
To determine which of these options a virus needs in order to multiply, we can examine each option and evaluate its relevance.
1. A host cell to provide oxygen for the virus: Viruses do not require oxygen for their replication. They are not metabolically active and do not undergo respiration or use oxygen. Therefore, this option is not correct.
2. Chloroplasts from a host cell: Chloroplasts are only found in plant cells and some protists. Viruses primarily infect animal cells, and they do not require chloroplasts for their replication. Thus, this option is not correct.
3. A host cell to replicate the virus’s DNA: Viruses are unable to replicate on their own and rely on host cells to provide the necessary machinery and resources for replication. They hijack the host cell's machinery to replicate their DNA or RNA. Therefore, this option is correct.
4. New ADP from a host cell: ADP (adenosine diphosphate) is a molecule involved in cellular energy metabolism. However, viruses do not require new ADP from a host cell to multiply. They do not have their own energy metabolism and rely on the host cell's resources. Therefore, this option is not correct.
Based on the evaluation above, the correct answer is: A host cell to replicate the virus’s DNA.
