lysogeny
Học thuậtThân thiện
A scientist observes a bacterial culture in a state of lysogeny under a microscope.
Definition
Noun: * A state of peaceful coexistence between a bacteriophage and its bacterial host: Lysogeny describes the condition where the genetic material of a virus (a bacteriophage) is integrated into the chromosome of a bacterium. The viral genes are replicated along with the host's DNA without immediately destroying the cell. The virus in this inactive, integrated form is called a prophage.
Examples of Usage
- Noun:
- The phenomenon of lysogeny allows the viral DNA to be passed on to the bacterial progeny.
- In a state of lysogeny, the bacterium is not harmed by the phage.
- The switch from lysogeny to the lytic cycle can be triggered by environmental stress.
Advanced Usage
- "Maintain lysogeny": Refers to the stable, inherited state where the prophage remains integrated.
- The phage repressor protein is crucial to maintain lysogeny.
- "Establish lysogeny": Describes the process by which an infecting phage integrates into the host genome to begin this dormant state.
- After infection, the lambda phage must decide whether to establish lysogeny or enter the lytic cycle.
Variants and Related Words
- Lysogen (n): The bacterium that harbors a prophage and is in a state of lysogeny.
- A lysogen can spontaneously produce phage particles.
- Lysogenic (adj): Pertaining to or characterized by lysogeny.
- The lysogenic cycle is one of two life cycles of temperate phages.
- Lysogenize (v): To cause a bacterium to become a lysogen.
- The temperate phage can lysogenize its host.
- Prophage (n): The latent, integrated form of a bacteriophage in a lysogenic bacterium.
Synonyms
- Lysogenic state: The condition of lysogeny.
- Prophage state: Emphasizes the presence of the integrated prophage.
Related Concepts (Not Phrasal Verbs/Idioms)
- Lytic cycle: The alternative viral life cycle that results in the lysis (destruction) of the host cell, contrasted with lysogeny.
- Temperate phage: A type of bacteriophage capable of entering the lysogenic cycle.
- Induction: The process that triggers a prophage to exit lysogeny and initiate the lytic cycle.

Noun
- the condition of a host bacterium that has incorporated a phage into its own genetic material
- when a phage infects a bacterium it can either destroy its host or be incorporated in the host genome in a state of lysogeny
