lysogeny

Examples of lysogeny in the following topics:

• Plasmids and Lysogeny

  • Both plasmids and lysogeny are used by bacteria and viruses to ensure transfer of genes and nucleic acids for viral reproduction.
  • Lysogeny is the process by which a bacteriophageintegrates its nucleic acids into a host bacterium's genome.
  • Lysogeny is utilized by viruses to ensure the maintenance of viral nucleic acids within the genome of the bacterium host.
  • Lysogeny is one of two major methods of viral reproduction utilized by viruses.
  • An example of a virus which can promote the transformation of bacterium from a nontoxic to toxic strain via lysogeny is the CTXφ virus.

• Temperate Bacteriophages: Lambda and P1

  • With phage the term virulent is often used as an antonym to temperate, but more strictly a virulent phage is one that has lost its ability to display lysogeny through mutation, rather than a phage lineage with no genetic potential to ever display lysogeny (which more properly would be described as an obligately lytic phage).
  • In lysogeny, P1 can exist within a bacterial cell as a circular DNA, in that it exists by replicating as if it were a plasmid and does not cause cell death.
  • During lysogeny, new phage particles are not produced.
  • A unique feature of phage P1 is that during lysogeny its genome is not incorporated into the bacterial chromosome, as is commonly observed during lysogeny of other bacteriophage.
  • This virus is temperate and may reside within the genome of its host through lysogeny.

• Bacteriophage Lambda as a Cloning Vector

  • This virus is temperate and may reside within the genome of its host through lysogeny.

• Overview of Bacterial Viruses

  • Those phages able to undergo lysogeny are known as temperate phages.

• Culture Media

  • The most common growth media nutrient broths (liquid nutrient medium) or LB medium (Lysogeny Broth) are liquid.
