The coding (sense) strands of two complete (double-stranded) DNA molecules have the base sequences shown in the table below. Two replication experiments are done with each molecule: 1. In Experiment #1, samples of each DNA molecule are incubated with radioactive thymine, along with appropriate replication enzymes, ATP, adenine, thymine, and cytosine.

Question
The coding (sense) strands of two complete (double-stranded) DNA molecules have the base sequences shown in the table below. Two replication experiments
are done with each molecule:
1. In Experiment #1, samples of each DNA molecule are incubated with radioactive thymine, along with appropriate replication enzymes, ATP, adenine,
thymine, and cytosine.
Experiment #1 is stopped when each DNA molecule has replicated once.
2. In Experiment #2, all the DNA molecules from #1 are purified, and then incubated with again with the same reaction mixture.
Experiment #2 is stopped when each DNA molecule has replicated one more time.
Predict the percentage of DNA in each sample that radioactive after each experiment. Round your answers to the nearest percent.
