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.
How many stages are there in the lytic cycle?
The Lytic Cycle There are five stages in the bacteriophage lytic cycle (see Figure 6.2. 1).
What are the steps of the lytic cycle quizlet?
Name the 5 steps in the Lytic Cycle in order.
- Attachment.
- Penetration.
- Biosynthesis.
- Maturation.
- Release.
What are the 5 stages of viral infection?
The life cycle of viruses can differ greatly between species and category of virus, but they follow the same basic stages for viral replication. The viral life cycle can be divided into several major stages: attachment, entry, uncoating, replication, maturation, and release.
What are the steps of lytic infection?
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 5 steps of viral infection?
The life cycle of viruses can differ greatly between species and category of virus, but they follow the same basic stages for viral replication. The viral life cycle can be divided into several major stages: attachment, entry, uncoating, replication, maturation, and release.
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 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 are the 5 stages of the disease process?
The five periods of disease (sometimes referred to as stages or phases) include the incubation, prodromal, illness, decline, and convalescence periods (Figure 2). The incubation period occurs in an acute disease after the initial entry of the pathogen into the host (patient).
What are the five classifications of infectious diseases?
Classification of Infectious Diseases
- Bacterial infectious diseases.
- Viral infectious diseases.
- Parasitic infectious diseases.
- Fungal infectious diseases.
- Mycobacterial diseases.
- Air borne diseases.
- Food borne diseases.
- Water borne diseases.
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 stages of infection?
The natural history of an untreated communicable disease has four stages: stage of exposure, stage of infection, stage of infectious disease, and stage of outcome.
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 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 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 are the 4 stages of the natural history of a disease or health condition?
Events that occur in the natural history of a communicable disease are grouped into four stages: exposure, infection, infectious disease, and outcome (see Figure 1.6).
What are the five causes of disease?
Causes
- Bacteria. These one-cell organisms are responsible for illnesses such as strep throat, urinary tract infections and tuberculosis.
- Viruses. Even smaller than bacteria, viruses cause a multitude of diseases ranging from the common cold to AIDS.
- Fungi. …
- Parasites.

What are the five signs of an infection?
Know the Signs and Symptoms of Infection
- Fever (this is sometimes the only sign of an infection).
- Chills and sweats.
- Change in cough or a new cough.
- Sore throat or new mouth sore.
- Shortness of breath.
- Nasal congestion.
- Stiff neck.
- Burning or pain with urination.
How does the lytic cycle work?
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 are the 5 modes of transmission?
Modes of transmission
- Direct. Direct contact. Droplet spread.
- Indirect. Airborne. Vehicleborne. Vectorborne (mechanical or biologic)
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.
How does a virus take over a host cell 5 steps?
The virus life cycle could be divided into six steps: attachment, penetration, uncoating, gene expression and replication, assembly, and release.
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 are the 8 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 4 stages of pathogenesis?
Stages of Pathogenesis. To cause disease, a pathogen must successfully achieve four steps or stages of pathogenesis: exposure (contact), adhesion (colonization), invasion, and infection.
What are the 5 most common infectious diseases?
