Given two oligo-deoxynucleotides, the task is to determine the composition of the newly synthesized DNA strand using radiolabeled nucleotides. The correct answer indicates the ratio of adenine (A), thymine (T), cytosine (C), and guanine (G) in the newly formed DNA, which is derived from the complementary base pairing with the provided templates."}
