BIOL 2200 - Exam II Practice Questions With Complete Solutions Which of the following statements correctly answers how the large amount of genetic variation observed in prokaryotes arises? A) The mutation rate in prokaryotes is much higher than in eukaryotes. B) They have extremely short generation times and large populations. C) They can exchange DNA with many types of prokaryotes by way of horizontal gene transfer. D) They have a relatively small genome. ️️ B and D The short generation times and large population sizes in most prokaryotic species, coupled with their ability to exchange genes, help to increase genetic variability beyond what we would expect in asexually reproducing organisms. Can you distinguish among the three processes of genetic transfer in bacteria? ️️ Conjugation only: - involves the transfer of DNA from an Hfr cell to an F- cell - requires cell-to-cell contact
