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.

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.
When viruses synthesize proteins what form of genetic information is used?
Messenger RNA
Are viruses living cells?
No, they are not alive at all.
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."
Do viruses produce cellular proteins?
Viruses do produce cellular proteins that are necessary for viral synthesis.
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.
True of false when a virus is active the cell makes the virus's proteins and genetic material and new viruses are made?
True. When a virus is active, it hijacks the cell's machinery to replicate its genetic material and synthesize its proteins. This process leads to the assembly of new viruses within the host cell.
The basic components of all viruses are a nucleic acid and what other structure?
fg
Why does a virus not have both DNA and RNA?
Viruses contain either DNA or RNA, not both, because they are simpler organisms that do not require both types of genetic material. Having both DNA and RNA would make the virus more complex and potentially less efficient at replicating within a host cell.
Viruses must reproduce in a cell because they lack organelles needed to duplicate viral components?
. Viruses must reproduce in a host cell because they lack organelles needed to duplicate viral components. True or false
why viruses are acellur?
Viruses are acellular, which means they don't have a cellular structure. As a result, they lack the majority of cell components such as organelles, ribosomes, and the plasma membrane.
