|
prokaryotic cells have less DNA than do eukaryotic cells.
|
|
|
Unlike eukaryotic cells, prokaryotic cells do not have a nucleus.
|
|
|
The cell wall in prokaryotic cells is a less effective barrier.
|
|
|
The rapid growth of prokaryotic cells generates more viruses.
|
Detailed explanation-1: -Explanation: DNA in eukaryotic cells lies within the nucleus. This DNA has a membrane protecting it from the outside. This means that the virus will have a harder time at getting to the DNA to insert its own DNA into it.
Detailed explanation-2: -Why might it be simpler for these viruses to attack prokaryotic cells than eukaryotic cells? prokaryotic cells have less DNA than do eukaryotic cells. Unlike eukaryotic cells, prokaryotic cells do not have a nucleus. The cell wall in prokaryotic cells is a less effective barrier.
Detailed explanation-3: -A virus must enter a living cell and take over the cell’s machinery in order to reproduce and make more viruses. Some viruses do this by inserting their own DNA (or RNA) into that of the host cell. When the DNA or RNA affects the host cell’s genes, it can push the cell toward becoming cancer.
Detailed explanation-4: -Viruses can use either prokaryotes or eukaryotes, or both, as host cells. To do so, the virus injects its genetic material into the host, which then triggers the host to begin replicating the virus’s genetic material.
Detailed explanation-5: -Virus entry into animal cells is initiated by attachment to receptors and is followed by important conformational changes of viral proteins, penetration through (non-enveloped viruses) or fusion with (enveloped viruses) cellular membranes. The process ends with transfer of viral genomes inside host cells.
