Conjugation can be used to map bacterial genes by mixing Hfr and F - cells of different genotypes and interrupting conjugation at regular intervals. The amount of time required for individual genes to be transferred from the Hfr to the F - cells indicates the relative positions of the genes on the bacterial chromosome.
-Interrupted conjugation was used to map three genes in E. coli. The donor genes first appeared in the recipient cells at the following times: gal, 10 minutes; his, 8 minutes; pro, 15 minutes. Which gene is in the middle?
