Differbetween
The main difference between prophage and provirus is that prophage is the viral genome integrated into a bacterial genome, whereas provirus is the viral genome integrated into a eukaryotic genome.

What is the difference between a phage and a prophage?
Virulent phage: Phage which displays only lytic cycles (no chronic or lysogenic cycles). Temperate phage: Phage which can undergo either virion-productive or lysogenic cycles. Prophage: Phage genome that replicates with its host cell while not generating virion progeny.
What does Provirus mean?
: a form of a virus that is integrated into the genetic material of a host cell and by replicating with it can be transmitted from one cell generation to the next without causing lysis.
What is the main difference between the lytic and lysogenic cycle?
The difference between lysogenic and lytic cycles is that, in lysogenic cycles, the spread of the viral DNA occurs through the usual prokaryotic reproduction, whereas a lytic cycle is more immediate in that it results in many copies of the virus being created very quickly and the cell is destroyed.
What is the prophage?
: an intracellular form of a bacteriophage in which it is harmless to the host, is usually integrated into the hereditary material of the host, and reproduces when the host does.
Is prophage a virus?
A prophage is a bacteriophage (often shortened to "phage") genome inserted and integrated into the circular bacterial DNA chromosome or exists as an extrachromosomal plasmid. This is a latent form of a phage, in which the viral genes are present in the bacterium without causing disruption of the bacterial cell.
Do viruses kill bacteria?
Bacteriophages (phages) are viruses of bacteria that can kill and lyse the bacteria they infect. After their discovery early in the 20th century, phages were widely used to treat various bacterial diseases in people and animals.
What is an example of a Provirus?
An inactive viral form that has been integrated into the genes of a host cell. For example, when HIV enters a host CD4 cell, HIV RNA is first changed to HIV DNA (provirus).
Does Ebola form a Provirus?
Ebola virus takes advantage of a non-specific engulfing process called macropinocytosis, which allows the virus to be “eaten” by a wave-like motion of the cell membrane (Figure 1) [2]. Once inside the cell, the virus hijacks the cell's own machinery to create more copies of itself.
What are two alarming characteristics of prions?
What are two alarming characteristics about prions? they act very slowly and have a 10 year incubation period, this makes it hard to identify the source of the infection. also they are virtually indestructable and their is no known cure for any prion diseases.
What are the 5 stages of the lytic cycle?
These stages include attachment, penetration, uncoating, biosynthesis, maturation, and release. Bacteriophages have a lytic or lysogenic cycle. The lytic cycle leads to the death of the host, whereas the lysogenic cycle leads to integration of phage into the host genome.
Which is more dangerous lytic or lysogenic?
The lysogenic cycle is much slower and may not infect a host body as fast as the lytic cycle might, but it can still be just as deadly. Instead of replicating many copies of itself after it has inserted itself into a cell, the viral DNA (or RNA) incorporates itself into the genome of the cell, staying hidden.
What are the 7 steps of the lysogenic cycle?
