The  following must be true about strands 1 and 2 in the replicated DNA: \"1\" must be at the 5\' end of the DNA strand \"2\" must be at the 5\' end of the DNA strand You can\'t determine the whether \"1\" or \"2\" are at the 5\' or 3\' end of the strands of DNA.

Solution

Answer: (B)

\"2\" denotes the newly synthesized strand and synthesizes the DNA in the 5\' to 3\' direction of the newly synthesized DNA. The primer initiating the replication of the new DNA strand binds to the 3\' end of the parental DNA strand and replicates in the 5\' to 3\' direction (newly replicated DNA).
