What are the steps of the lytic cycle in order?
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 are the steps of the lytic cycle quizlet?
Name the 5 steps in the Lytic Cycle in order.
- Attachment.
- Penetration.
- Biosynthesis.
- Maturation.
- Release.
Which is a step in the replication cycle of a lytic virus?
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 are the 4 steps of the lytic cycle?
The lytic cycle involves four steps: infecting a host (an action called exposure), injecting a cell with the virus's genetic material, using the cell's metabolic engines to create new viruses, and finally, weakening the cell walls until the host cell lyses, or bursts open from excessive internal pressure.
What are the 4 steps of the lysogenic cycle?
The following are the steps of the lysogenic cycle:1) Viral genome enters cell2) Viral genome integrates into Host cell genome3) Host cell DNA Polymerase copies viral chromosomes4) cell divides, and virus chromosomes are transmitted to cell's daughter cells5) At any moment when the virus is "triggered", the viral …
What are the 5 steps of bacteriophage replication quizlet?

- 1- attachment. attach to the cell.
- 2-penetration. only nucleic acid is injected into the cell through the hole caused by the tail fibers and enzymes.
- 3- synthesis. replication of viral nucleic acid and protein and envelope.

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 first step in the lytic cycle?
Lytic cycle steps. Phage attachment. In order to enter a host bacterial cell, the phage must first attach itself to the bacterium (also called adsorption). Initial contact between phage and bacterium often happens through random collisions and initial binding is reversible.
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 are the steps of the lytic and lysogenic cycle?
In the lytic cycle, the phage replicates and lyses the host cell. In the lysogenic cycle, phage DNA is incorporated into the host genome, where it is passed on to subsequent generations. Environmental stressors such as starvation or exposure to toxic chemicals may cause the prophage to excise and enter the lytic cycle.
What does the lytic cycle do?
What is 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 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 occurs in the lysogenic cycle?
In the lysogenic cycle, the DNA is only replicated, not translated into proteins. In the lytic cycle, the DNA is multiplied many times and proteins are formed using processes stolen from the bacteria.
What is the last step 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 are the 7 steps to the lysogenic cycle?
The following are the steps of the lysogenic cycle:1) Viral genome enters cell2) Viral genome integrates into Host cell genome3) Host cell DNA Polymerase copies viral chromosomes4) cell divides, and virus chromosomes are transmitted to cell's daughter cells5) At any moment when the virus is "triggered", the viral …
What occurs during the biosynthesis stage of the lytic cycle of a bacteriophage quizlet?
What happens during Biosynthesis in the lytic cycle? Production of bacteriophage nucleic acids and proteins using host cellular machinery and ingredients. Host DNA degraded by viral enzymes, many copies of viral nucleic acid are made.
What is the first step of a virus life cycle?
The first stage is entry. Entry involves attachment, in which a virus particle encounters the host cell and attaches to the cell surface, penetration, in which a virus particle reaches the cytoplasm, and uncoating, in which the virus sheds its capsid.
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 are the 4 basic steps of the lytic cycle?
The lytic cycle involves four steps: infecting a host (an action called exposure), injecting a cell with the virus's genetic material, using the cell's metabolic engines to create new viruses, and finally, weakening the cell walls until the host cell lyses, or bursts open from excessive internal pressure.
What is lytic replication?
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.

What are the 5 steps of viral replication?
Main steps of viral replication These include attachment, penetration, uncoating, replication, assembly, and virion release.
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 is the correct order of steps in viral replication?
Viral replication involves six steps: attachment, penetration, uncoating, replication, assembly, and release. During attachment and penetration, the virus attaches itself to a host cell and injects its genetic material into it.
What are the steps involved in viral replication quizlet?

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.
What are the 7 steps of viral replication?
As discussed above, they are carried out in a series of 7 steps that is: attachment, penetration and entry, uncoating, replication, synthesis of virus components, assembly of virions and lastly the release of virions.
