Definition of prophage in English: prophagenoun ˈprəʊfeɪdʒˈprōˌfāj Microbiology The genetic material of a bacteriophage, incorporated into the genome of a bacterium and able to produce phages if specifically activated. Example sentencesExamples - This phenomenon is similar to suicidal defense against phage infection, or phage exclusion, programmed by prophages and plasmids, and may well play a similar role.
- It is now known that phages produced by lysogenic bacteria are of the temperate type and that part of the infected bacteria do not lyse but maintain the phage in a latent form called a prophage (lysogenic response).
- The incorporation of plasmids or prophages into the bacterial chromosomes is called transfection.
- To visualize the expression of genes of all 10 prophage and prophage-like regions, the DNA macro-array technique was used.
- Specialized transducing phages generated from the prophage by illegitimate recombination usually contain the E. coli genes gal or bio that are adjacent to the phage genome.
Origin 1950s: from pro-2 'before' + phage.
