WebSeveral groups of bacteria, including Brucella, Paracoccus denitrificans, and Vibrio have multiple circular chromosomes. Many Alphaproteobacteria have two circular molecules. In some cases, such as Brucella melitensis, … WebJan 3, 2024 · Over time, many bacterial genes were mapped all along the E. coli chromosome by isolating many different Hfr strains in which an F plasmid had inserted into different sites around the DNA circle. These Hfr strains were mated to F- bacteria, each with mutations in one or another known bacterial gene.
