WebA simplified linkage map of circular E. coli chromosome constructed from interrupted mating experiment is shown in Fig. 8.14. It takes about 100 minutes to transfer the entire E. coli chromosome. Therefore, the genes are mapped relative to the position of the integrated F plasmid by determining the time taken by the gene to be transferred to the … WebIn an interrupted mating conjugation experiment in E. Coli, an Hfr strain was used to provide mapping information for four markers (genes). The time of entry for the transfer of the four markers from the Hfr strain to the F - strain was found to be: Arg – 6 minutes Ser – 21 minutes Leu – 29 minutes Thr – 35 minutes Draw a map of the E. Coli chromosome …

Web18. Rarely, conjugation of Hfr and F – cells produces two Hfr cells. Explain how this occurs. Hfr strains contain an F factor integrated into the bacterial chromosome. The F factor mediates transfer of the bacterial chromosome. During conjugation of an Hfr strain with an F – strain, the transfer process begins within the F factor. So literally, part of the F factor …
