In the year 1963, the two enzymes responsible for restricting the growth of bacteriophage in E. coli were isolated. One of these added methyl groups to DNA, while the other cut DNA. The latter was called

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
