WebInterrupted mating experiments use the process of conjugation to map the order of genes on a bacterial chromosome. In conjugation, the donor cell’s chromosome gets pushed slowly through a sex pilus as a single linear strand until it enters the recipient cell. WebDec 7, 2015 · Interrupted mating The length of time a mating occurs, the more DNA is transferred The Hfr DNA is transferred in a linear manner By mating for different times, you can get DNA of several sizes, and determine the order of the genes, and how far apart they are (minutes) 25.
