The viral reproductive cycle in which a phage injects its DNA into a host cell and the DNA is inserted into the host cells chromosome is called the what cycle?
Lytic :D -Gotta help out my fellow Plato users.
The viral reproductive cycle in which a phage injects its DNA into a host cell and uses the cell's metabolic machinery to produce new phages which then causes the cell to rupture is called what cycle?
The Lytic Cycle. See related questions below for more information.
What does it mean for a virus to have a lysogenic reproductive cycle?
The lysogenic cycle replicates the phage genome without destroying the host. Similar to Lytic reproduction, Lysogenic also begins when the phage inserts its DNA or RNA into the host cell through its surface. Once the nucleic acid is inside the cell, it forms a circle, and becomes a part of the genome of the host cell. It does this through genetic recombination, or crossing over. Once it joins the host’s genome, it is called a prophage. Since it is a part of the host cell’s genome, the phage’s genetic information is copied and distributed to the daughter cells of the host cell, which continues dividing naturally. This allows the prophage to be repeatedly copied and passed on without destroying the host cell it depends on for metabolic and reproduction purposes. In order for actual active phages to be produced, the segment of genome from the original phage exits the genome of the host cell and becomes independent. When this occurs, it begins the lytic cycle, destroying the cell, but producing new and functional phages.
Why is a virus's reproduction cycle called the lytic cycle?
Lysis means cut open or split, the word lytic comes from lysis. In the lytic cycle, the host cells that have been infected by a virus will fill up with new viruses until they gets too full and then they split open to release the new viral particles, and the cell dies. See more about the lytic cycle in the related questions below.
What is the difference between a virulent phage and a temperate phage?
In virology, temperate refers to the life cycle some phages are able to perform. Atemperate phage can integrate its genome into its host bacterium's chromosome, becoming a lysogen known as a prophage. A temperate phage is also able to undergo lytic life cycles, where the prophage is expressed, replicates the phage genome and produces phage progeny and the progeny phage leave the bacterium. The virulent phages have only lytic lifecycles and thus infection results in the host cell's death (due to lytic cell destruction-the phage replicates itself and then bursts the cell, releasing many copies).
The viral reproductive cycle in which a phage injects its DNA into a host cell and the DNA is inserted into the host cells chromosome is called the?
motor cycle
The viral reproductive cycle in which a phage injects its DNA into a host cell and the DNA is inserted into the host cell's chromosome is called the cycle?
B) Lysogenic
What happens first when a phage infects a bacterial cell and is going to enter a lysogenic cycle?
it becomes a part of the bacterial DNA and it can be replicated into the daughter cells. this cycle doesn't harm the bacterial cell but it can change into the lysis cycle and kill the host cell
The viral reproductive cycle in which a phage injects its DNA into a host cell and the DNA is inserted into the host cell's chromosome is called the?
lysogenic
How does the reproduction of HIV and lambda phage differ?
The Lambda Phage bacterial virus replicates itself whilst the HIV virus binds itself to existing cells and damages them. Lamba Phage increases with a "lysogenic" cycle, whilst the increase of HIV is known as "Lytic".
When the bacteriophage DNA becomes part of the bacterial chromosome?
During phage infection into bacteria, it penetrates phage DNA into bacterium,which will be integrated in to the bacterial genome (chromosome) to replicate and synthesize phage molecules.

When a T2 bacteriophage infects an E. coli cell what part of the phage enters the bacterial cytoplasm?
the whole phage
The viral reproductive cycle in which a phage injects its DNA into a host cell and uses the cell's metabolic machinery to produce new phages which then causes the cell to rupture is called what cycle?
The Lytic Cycle. See related questions below for more information.
What happens when a bacteriophage infects a bacteria cell?
When a bacteriophage infects a bacteria it enters either the lyctic or lysogenic cycle. the lyctic is the stages of: injection, reproduction, host destruction. The lysogenic cycle is when the virus' RNA mixes with the host cell's.
Phage typing is based on the fact that?
Bacterial viruses attack specific cells
What is the function of bacteriophage?
The function of bacteria is to reproduce. Bacteria is a large domain of prokaryotic microorganisms. They are also the cause of human and animal diseases. Some bacteria, like those in the intestines are friendly and needed for digestion.
