Examples
-
In 1950 André Lwoff and his colleagues created the term prophage by discovering lysogenic bacteriophages inside Bacillus megaterium using ultra-violet light.
-
Now then, the prophage is reproduced by bacterial enzymes.
-
The prophage is attached to the bacterial chromosome.
-
The term "prophage" was therefore proposed, and it seemed that the world eagerly awaited its coming.
-
Viral HGT is mediated by bacteriophage enzymes that insert the gene into the genome (normally for a prophage, but where it picks up genes and does it is a different story).
-
While working as a research associate with Bertani, I received P1 at first hand which enabled me to study phage Pl-mediated transduction of monomeric and dimeric lambda prophage genomes as well as of the fertility plasmid F.
-
By 1967, I had published this work and had carried out a study of defective transducing particles formed after induction of int mutant prophage.
-
In 1965, we discovered the gene controlling prophage attachment, now known as the int gene.
-
Stimulated by Jean Weigle we soon turned our interests also to other properties of lambda, and the study of defective lambda prophage mutants became the topic of my doctoral thesis.
-
Since these investigators had encountered defective lysogenic strains among their transductants, we felt that such strains should be included in the collection of lambda prophage mutants under study in our laboratory.
