- The figure below shows a partial chromosome map of an E. coli Hfr strain. Each mark = 10 minutes between conjugation transfer time. If transfer of genes begins at “*” relative to the origin of transfer, what is one of the predicted results from this map? It would take less than 30 minutes to transfer all of the genes that are shown. gal and azi will rarely be transferred together. gal and ton will rarely be transferred together. Ten minutes after transfer of ton, lac will be transferred. This strain will produce very few gal recombinants.arrow_forwardAside from the bacterial chromosome where may DNA be found in a prokaryotic cell and what ways is genetic material transferred from one bacterial cell to another?arrow_forwardWhy can transfer of DNA by conjugation cross genus lines, whereas transfer of DNA by natural transformation or phage transduction is usually limited to a few closely related organisms?arrow_forward
