A.cell is grown in a solution which contain radioactive nucleotides, so that DNA is labelled with radioactivity . It is issolated from the radioactive solution and grown in a normal medium. So that any new DNA strands it makes will not be radioactive. the cell replicates its DNA and divides in the normal medium . the two daughter cell also replicates their DNA and divide, producing a total four cell. if a dotted line represent a radioactive DNA strand and a solid line repreesents a nonradioactive DNA strand, which of the following depicts the DNA of the four cell
