Since viruses are not living, they have to somehow highjack the DNA of a living cell. They then use their DNA or RNA to give instructions to make virus parts instead of the normal cell parts. Once the parts are assembled, the viruses crowd the cell and break free, killing the cell, to do it again and again.
What else can I help you with?
Why does a virus need energy?
Viruses do not directly need energy. The virus takes control of the host cell in order to replicate. The host cell's own metabolic machinery is used to synthesize the components of new viruses. The virus itself is passive.
Why do viruses need the equipment of the host cell in order to reproduce?
Viruses lack the cellular machinery and metabolic processes necessary for replication, so they must hijack the host cell's resources to reproduce. They use the host's ribosomes, enzymes, and energy to synthesize their own components, such as proteins and genetic material. This dependence on the host's cellular machinery is why viruses are considered obligate intracellular parasites, meaning they can only replicate inside living cells. Without the host's equipment, viruses cannot reproduce or propagate.
When viruses synthesize proteins what form of genetic information is used?
Messenger RNA
How do viruses build macromolecules?
Viruses lack the cellular machinery to synthesize macromolecules independently; instead, they hijack the host cell's biosynthetic processes. Once a virus infects a host cell, it releases its genetic material, which directs the host's ribosomes and enzymes to produce viral proteins and replicate viral RNA or DNA. These components then assemble into new viral particles, effectively utilizing the host's resources to generate the necessary macromolecules for the virus's life cycle.
Are viruses living cells?
No, they are not alive at all.
Do viruses produce cellular proteins?
Viruses do produce cellular proteins that are necessary for viral synthesis.
Can a smaller virus affect a bigger virus?
No because a virus is simply genetic material coated in a protein shell. Internally, viruses do not have the components, which are commonly found in cells, necessary to propagate "offspring."
What are the two basic components of viruses?
The two basic components of viruses are genetic material (either DNA or RNA) and a protein coat that surrounds and protects the genetic material.
Why are viruses made of cells?
Viruses are made of cell parts because they cannot synthesize the materials without a host cell. Protein coats and the material for the nucleic acid are taken entirely from the host cell using its energy.
Why does a virus not have both DNA and RNA?
Because it doesn't use it's DNA or RNA to function, it uses it to inject into a cell and switch the cell's instructions to its own so the cell will make more viruses. Cells have DNA and RNA to tell the cell what to do, but viruses just do it naturally. Viruses have no use for both.
True of false when a virus is active the cell makes the virus's proteins and genetic material and new viruses are made?
The components of the new virus actually assemble them selves through a complex process called "Self Assembly"
The basic components of all viruses are a nucleic acid and what other structure?
