What happens to bacterial DNA in lytic cycle?

In the lytic cycle, the DNA is multiplied many times and proteins are formed using processes stolen from the bacteria. While the lysogenic cycle can sometimes happen in eukaryotes, prokaryotes or bacteria are much better understood examples. A bacteriophage, or bacteria virus, injects its DNA into the bacteria.

What happens in each stage 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 happens to the viral DNA during the lysogenic cycle?

During lysogeny, the prophage will persist in the host chromosome until induction, which results in the excision of the viral genome from the host chromosome. After induction has occurred the temperate phage can proceed through a lytic cycle and then undergo lysogeny in a newly infected cell (see Figure 6.2.

What are the five steps of the lytic cycle?

Which of the following events occurs during the lytic life cycle of phages?

During the lytic cycle of virulent phage, the bacteriophage takes over the cell, reproduces new phages, and destroys the cell.

Which enzyme inserts viral DNA into the host’s chromosomal DNA?

Integrase Integrase is the viral enzyme that catalyzes the integration of virally derived DNA into the host cell DNA in the nucleus, forming a provirus that can be activated to produce viral proteins.

What happens during the lytic cycle of a viral infection?

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.

Which of the following occurs during a lysogenic cycle?

which of the following occurs during a lysogenic cycle? viral DNA is replicated and the host cell is not destroyed. this cycle results in the host cell breaking open and the realease of more viruses.

What is lytic process?

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 the steps of the lytic cycle quizlet?

Name the 5 steps in the Lytic Cycle in order.

Attachment.
Penetration.
Biosynthesis.
Maturation.
Release.

What happens to the host bacteria’s DNA after the bacteriophage injects its DNA RNA into the cell?

What happens to the host bacteria's DNA after the bacteriophage injects its DNA/RNA into the cell? It puts the viruses DNA into the cells own DNA. The bacteria pass this "combined" DNA on to the daughter cells. The bacteria continue to reproduce and finally enter the lytic cycle when this happens.

What are the steps in the lytic cycle of bacteriophages and what occurs during each step?

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.

Which enzyme inserts viral DNA into the host’s chromosomal DNA quizlet?

Which enzyme inserts viral DNA into the host's chromosomal DNA? Integrase inserts viral DNA into the host's chromosomal DNA. How does HIV bind to a host cell? The viral envelope proteins interact with CD4 and a co-receptor on the cell membrane.

How is viral DNA inserted into the host DNA?

Once the preintegration complex associates with the host chromosome, viral IN catalyzes the insertion of the viral sequences into the host DNA. The two LTR ends of the linear viral DNA are brought together into a ternary complex with IN and host DNA, where the insertion occurs in a coordinated or concerted reaction.

What is a lytic process?

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.

Which of the following occurs during the lytic cycle?

What makes the lysogenic cycle different from the lytic cycle?

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. Viral DNA destroys the host cell DNA and arrests the cell functions in the lytic cycle. However, in the lysogenic cycle, viral DNA may merge with the host DNA.

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 steps in the lytic cycle?

10.7A: The Lytic Life Cycle of Bacteriophages

Step 2: Penetration.

What happens at the end of the lytic cycle quizlet?

What always happens to the host cell at the end of the Lytic cycle? The cell bursts and releases 100's of new viruses.

When the bacteriophage DNA becomes part of the bacterial chromosome?

Phage DNA recombines with bacterial chromosome and becomes integrated into the chromosome as a prophage. Cell division. Each time a cell containing a prophage divides, its daughter cells inherit the prophage.

What would be the fate of a lytic bacteriophage if the host cell died prior to the assembly stage?

What would be the fate of a lytic bacteriophage if the host cell died prior to the assembly stage? The virus would infect new hosts.

Which of the following is characteristic of the lytic cycle?

Which of the following is characteristic of the lytic cycle? D) A large number of phages is released at a time.

Which occurs during the lytic cycle of a viral infection quizlet?

In the Lytic Cycle: VIRAL DNA DESTROYS CELL DNA, takes over cell functions and destroys the cell. The Virus replicates and PRODUCES PROGENY PHAGES.

How does lysogenic to lytic cycle transition occur?

Transition from lysogenic to lytic If a bacterium containing prophage is exposed to stressors, such as UV light, low nutrient conditions, or chemicals like mitomycin C, prophage may spontaneously extract themselves from the host genome and enter the lytic cycle in a process called induction.

What happens in both lytic and lysogenic cycle?

The daughter cells can continue to replicate with the prophage present or the prophage can exit the bacterial chromosome to initiate the lytic cycle. In the lysogenic cycle the host DNA is not hydrolyzed but in the lytic cycle the host DNA is hydrolyzed in the lytic phase.

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 happens in the lytic cycle 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. Bacteriophages that ONLY reproduce using the lytic cycle are called a VIRULENT PHAGES.

Is the host cell destroyed in the lytic?

In the lytic cycle (Figure 2), sometimes referred to as virulent infection, the infecting phage ultimately kill the host cell to produce many of their own progeny.
