What might cause a virus in a lysogenic cycle to suddenly enter the lytic cycle?
Stress in the host cell. Novanet.
How are the lysogenic and lytic cycles different?
causes Disease
What are two ways a virus can enter a host cell?
Viruses can cause lytic infections or lysogenic infections. When a virus enters a cell to make copies of itself, causing the cell to rupture, that is called a lytic infection. A lysogenic infection is where a virus incorporates itself into the DNA of the cell it invades and replicates its genetic code.
Do Active viruses enter a cell and immediatley begin to multiply?
The easiest way to understand how viruses replicate is to study the life cycles of viruses called bacteriophages (bacteria eaters). Bacteriophages replicate by either a lytic cycle or a lysogenic cycle. The difference in these two cycles is that the cell dies at the end of the lytic cycle or the cell remains in the lysogenic cycle. The virus remains "hidden".
What is true about a lysogenic infection?
Many viruses enter the lytic cycle immediately following infecting the host cell. However, some viruses may not lyse their host immediately and enter the lysogenic cycle. At the start of the lysogenic cycle, the virus genome is integrated into the host chromosome instead of being immediately transcribed and translated. The virus genome then lies dormant in the host chromosome until a later event triggers its excision from the host chromosome. The excised viral genome will then be transcribed and translated and the virus enters the lytic cycle. the virus hides in the host's DNA.
What are two ways that viruses cause infections?
The two ways that viruses cause infection are by lytic infection and lysogenic infection. The virus can enter into a cell, make a copy of itself and the cause the cell to burst in a lytic infection. When a virus embeds its DNA into the DNA of a host cell and replicates, it is a lysogenic infection.
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
HOW DOES A lysogenic infection help virus spread?
I don't know if this is what you are lookding for but here is what happens with a bacteriophage (a virus that infects bacteria) In a lysogenic infection the bactierophage DNA will insert itself into the bacterial chromosome and may replicate with the bacterium for many generations. (inactive) The bacteriohpage DNA can then exit the bacterial chromosome. If it does this then it can enter the LYTIC cycle.
Does depletion to the ozone layer cause changes in the bio-geochemical cycle?
The depletion of the ozone layer will cause UV to enter the earth. These will disturb the bio-chemical cycle.
How does a bacteriophage enter a bacterial?
Through a lysogenic or lytic infection
When virus enter a lysogenic phase it mean?
the virus is integrate inti the DNA of the host cell and is latent.
What are the two ways a virus multiplies?
A bacteriophage ( virus that infect bacteria) can multiply in a cell by two ways:lytic and lysogenic cycle.In lytic cycle, the phage DNA enters the cell, replicate and assembled within the cell and released outside by rupturing the host. It continues to invade the other bacteria.In case of lysogenic cycle the phage DNA once it enter the host cell gets integrated into the host genome and multiply along with host DNA. It remains latent. Upon proper induction, it undergoes lytic cycle again.The viruses that multiply by integrating into the host genome are widely used in gene therapy.
