Suppose that you performed a version of the Hershey and Chase experiment, this time using 32P-labelled viruses that insert their DNA into the DNA of the cells that they infect. Also suppose that the viral DNA is then treated as part of the cell's own DNA, and is replicated during DNA replication and passed on to daughter cells when the cell divides. You infect a population of cells with the 32P-labelled viruses, and then let the infected cells go through two generations of cell divisions. In how many cells should you find 32P-labelled DNA?
a. in none of them b. in about one-quarter of them c. in about one-half of them d. in about three-quarters of them
