lytic cycle

The lytic cycle (/ˈlɪtɪk/ LIT-ik) is one of the two cycles of viral reproduction (referring to bacterial viruses or bacteriophages), the other being the lysogenic cycle. The lytic cycle results in the destruction of the infected cell and its membrane.

What happens in 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 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 5 steps of the lytic cycle?

Terms in this set (5)

• 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.
• 4- assembly. ...
• 5- release.

Why is it called 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. ... In this way, the virus can continue replicating within its host.

Is lytic or lysogenic more dangerous?

The lysogenic cycle is much slower and may not infect a host body as fast as the lytic cycle might, but it can still be just as deadly. Instead of replicating many copies of itself after it has inserted itself into a cell, the viral DNA (or RNA) incorporates itself into the genome of the cell, staying hidden.

What are the 6 steps of the lytic cycle?

The six stages are: attachment, penetration, transcription, biosynthesis, maturation, and lysis.

Is lytic or lysogenic faster?

The difference between lysogenic and lytic cycles is that, in lysogenic cycles, the spread of the viral DNA occurs through the usual prokaryotic reproduction, whereas a lytic cycle is more immediate in that it results in many copies of the virus being created very quickly and the cell is destroyed.

What does lytic mean?

lytic (LIH-tik) Having to do with lysis. In biology, lysis refers to the disintegration of a cell by disruption of its plasma membrane. Lysis can be caused by chemical or physical means (e.g., high-energy sound waves) or by a virus infection.

Is the flu lytic or lysogenic?

THE OUTCOME OF VIRAL INFECTION

(1) The cell may lyse or be destroyed. This is usually called a lytic infection and this type of infection is seen with influenza and polio.

What is the final stage 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.

Does the lytic cycle kill the host?

Some phages can only reproduce via a lytic lifecycle, in which they burst and kill their host cells. Other phages can alternate between a lytic lifecycle and a lysogenic lifecycle, in which they don't kill the host cell (and are instead copied along with the host DNA each time the cell divides).

What is lytic infection?

Viral Reproduction—A Lytic Infection

Most viruses reproduce through a process called lytic infection. During lytic infection, a virus enters the host cell, makes a copy of itself, and causes the cell to burst, or lyse.
