What is the activation of a prophage called?

What is the activation of a prophage called?

Zygotic induction occurs when a bacterial cell carrying the DNA of a bacterial virus transfers its own DNA along with the viral DNA (prophage) into the new host cell. This has the effect of causing the host cell to break apart.

What does lysogeny mean?

Lysogeny refers to a process whereby a virus that specifically infects a bacterium, a bacteriophage (which means “devourer of bacteria”), achieves the manufacture of copies of its deoxyribonucleic acid (DNA ) genetic material by integrating the viral DNA into the DNA of the host bacteria .

Is it possible for a bacterial cell infected with temperate phage to replicate?

(a) A temperate phage can infect a cell through either virion-productive or lysogenic cycles, where it either hijacks its host’s metabolism to produce new virion progeny or instead replicates its genome alongside the host without producing new virions, respectively.

What term is used to specifically describe the types of viruses that infect bacteria?

bacteriophage, also called phage or bacterial virus, any of a group of viruses that infect bacteria.

What is prophage or temperate phage?

Temperate phage: Phage which can undergo either virion-productive or lysogenic cycles. Prophage: Phage genome that replicates with its host cell while not generating virion progeny.

What does a temperate phage do?

A bacteriophage that displays lysogenic life cycle in contrast to virulent phage that does not have the ability to display lysogeny (especially following mutation). Many temperate phages are capable of integrating their genome into the genome of their host.

What is lysogeny in microbiology?

lysogeny, type of life cycle that takes place when a bacteriophage infects certain types of bacteria. In this process, the genome (the collection of genes in the nucleic acid core of a virus) of the bacteriophage stably integrates into the chromosome of the host bacterium and replicates in concert with it.

Which phage is known as temperate phage?

P1 is a temperate bacteriophage (phage) that infects Escherichia coli and some other bacteria. When undergoing a lysogenic cycle, the phage genome exists as a plasmid in the bacterium, unlike other phages (e.g., the lambda phage) that integrate into the host DNA.

What is a temperate phage microbiology?

noun, plural: temperate phages. A bacteriophage that displays lysogenic life cycle in contrast to virulent phage that does not have the ability to display lysogeny (especially following mutation). Supplement. Many temperate phages are capable of integrating their genome into the genome of their host.

Why is it called temperate phage?

Viruses that replicate using only the lytic cycle are known as virulent bacteriophages, and viruses that replicate using both lysogenic and lytic cycles are known as temperate bacteriophages.

What is known as temperate phage?

In virology, temperate refers to the ability of some bacteriophages (notably coliphage λ) to display a lysogenic life cycle. Many (but not all) temperate phages can integrate their genomes into their host bacterium’s chromosome, together becoming a lysogen as the phage genome becomes a prophage.
