What are the steps in the lytic cycle?
Description. The lytic cycle, which is also commonly referred to as the "reproductive cycle" of the bacteriophage, is a six-stage cycle. The six stages are: attachment, penetration, transcription, biosynthesis, maturation, and lysis.

What is the lytic cycle quizlet?
Lytic Cycle. a viral reproductive cycle in which copies of a virus are made within a host cell, which then bursts open, releasing new viruses.
What is the lytic cycle of a virus?
In the lytic cycle, the virus attaches to the host cell and injects its DNA. Using the host's cellular metabolism, the viral DNA begins to replicate and form proteins. Then fully formed viruses assemble. These viruses break, or lyse, the cell and spread to other cells to continue the cycle.
What is the last step of the lytic cycle?
The final stage is release. Mature viruses burst out of the host cell in a process called lysis and the progeny viruses are liberated into the environment to infect new cells.
What is the first stage of the lytic cycle?
Lytic cycle steps. In order to enter a host bacterial cell, the phage must first attach itself to the bacterium (also called adsorption).
What are the 4 steps in the correct order of virus infection?
Entry, the first step of virus infection, involves the recognition of viral receptor by a virus particle. The viral entry can be divided into four steps: attachment, penetration, cytoplasmic trafficking, and uncoating.
What happens during the lytic cycle of viruses quizlet?
The LYTIC CYCLE is a viral reproductive cycle, during which a virus takes over all metabolic activities of a cell and causes the host cell to die.
What best describes the lytic and lysogenic cycles quizlet?
Which best describes the lytic and lysogenic cycles? Unlike the lysogenic cycle, the lytic cycle involves destruction of the host.
What is the lytic cycle simple definition?
The lytic cycle is named for the process of lysis, which occurs when a virus has infected a cell, replicated new virus particles, and bursts through the cell membrane. This releases the new virions, or virus complexes, so they can infect more cells.
What is the 3rd stage of the lytic cycle?
In the lytic cycle, the phage replicates and lyses the host cell. The third stage of infection is biosynthesis of new viral components. After entering the host cell, the virus synthesizes virus-encoded endonucleases to degrade the bacterial chromosome.
What is the lytic virus cycle?
In the lytic cycle, the virus attaches to the host cell and injects its DNA. Using the host's cellular metabolism, the viral DNA begins to replicate and form proteins. Then fully formed viruses assemble. These viruses break, or lyse, the cell and spread to other cells to continue the cycle.
What happens at the end of the lytic cycle?
Whilst the ultimate outcome of the lytic cycle is production of new phage progeny and death of the host bacterial cell, this is a multistep process involving precise coordination of gene transcription and physical processes.
What is the first step of the virus reproduction cycle?
Attachment is the first stage in the infection process in which the phage interacts with specific bacterial surface receptors (e.g., lipopolysaccharides and OmpC protein on host surfaces).
What happens in a lytic infection?
In a lytic cycle, the virus introduces its genome into a host cell and initiates replication by hijacking the host's cellular machinery to make new copies of the virus. Once infection is complete, the newly replicated and assembled virus particles are released through lysis of the host cell into the surrounding waters.
What best describes the lytic cycle?
Which best describes the lytic and lysogenic cycles? Unlike the lysogenic cycle, the lytic cycle involves destruction of the host.
What is the best description of the lytic cycle?
The lytic cycle is one of two cycles that a virus can use to reproduce inside a host cell. The lytic cycle is a series of stages in which a virus hijacks a host cell, uses its components to manufacture more of the virus, destroys and exits the cell, and then goes on to infect other cells.
What are the 5 stages of the viral life cycle?
The life cycle of virus. The virus life cycle could be divided into six steps: attachment, penetration, uncoating, gene expression and replication, assembly, and release.
How many steps are in the lysogenic cycle?
There are five main stages of the lysogenic cycle. There are as follows: The genome of the virus enters the host cell. Proteins of the host cell replicate the DNA normally read and then replicate the viral DNA and then virus creates a hole in its cell membrane and injected its DNA by the time this step is completed.
During which stage of the lytic cycle does the host cell lyse?
Stage 3: Replication. If the virus finds a permissive host it begins to replicate. Stage 4: Lysis. The virus causes the cell to burst, releasing the new viruses into the host's system.
What does lytic mean?
Listen to pronunciation. (LIH-tik) Having to do with lysis. In biology, lysis refers to the disintegration of a cell by disruption of its plasma membrane.
What are the 6 steps of lysogenic cycle?
Lysogenic cycle
- Attachment. Bacteriophage attaches to bacterial cell.
- Entry. Bacteriophage injects DNA into bacterial cell.
- Integration. Phage DNA recombines with bacterial chromosome and becomes integrated into the chromosome as a prophage.
- Cell division.
What is the lytic and lysogenic cycle?
The lytic cycle involves the reproduction of viruses using a host cell to manufacture more viruses; the viruses then burst out of the cell. The lysogenic cycle involves the incorporation of the viral genome into the host cell genome, infecting it from within.
What are the stages of lysogenic and lytic viral infection cycles?
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.
How lytic cycle is different from lysogenic?
Lytic cycle and the lysogenic cycle are two mechanisms of viral replication, which may occur interchangeably. The main difference between lytic cycle and lysogenic cycle is that lytic cycle destroys the host cell whereas lysogenic cycle does not destroy the host cell.
What does the lytic cycle do?
The lytic cycle involves the reproduction of viruses using a host cell to manufacture more viruses; the viruses then burst out of the cell. The lysogenic cycle involves the incorporation of the viral genome into the host cell genome, infecting it from within.
Why is it called a lytic cycle?
The lytic cycle is named for the process of lysis, which occurs when a virus has infected a cell, replicated new virus particles, and bursts through the cell membrane. This releases the new virions, or virus complexes, so they can infect more cells.
What are four ways that viruses may be transmitted spread?

- Spread through the air by droplets.
- Spread through the air by aerosol.
- Spread through faeces and then the mouth (faecal-oral spread)
- Spread by skin or mucous membrane contact.
- Spread through blood or other body fluids.
