etics: A Conceptual Approach 6th Edtion MHE/Freeman Phosphorous is required to synthesize the deoxyribonucleoside triphosphates used in DNA replication. A eneticist grows some E. col n a medium containing nonradioactive phosphorous for many generations sample of the bacteria is then transferred to a medium that contains a radioactive isotopé Samples of the bacteria are removed immediately after the transfer and after one and two rounds of replication. Assume that newly synthesized DNA contains 32p and the original DNA contains nonradioactive phosphorous. What will be the distribution of radioactivity in the DNA of the bacteria in each sample? Immediately after the transfer After one round of replication After two rounds of replication Both strands have P incorporated. one strand has P incorporated. 50% of the DNA molecules have 3P in one strand. 50% of the DNA molecules have 32P in both strands No 32P incorporated into the DNA.
