Figure 1 illustrаtes а mоdel оf the mоlecules involved in DNA replicаtion and their placement relative to each other. The D N A is coiled on the left side of the figure but separated into two single strands on the right side. The right end of the upper separated strand is labeled 3 prime, and the left end of the same strand, in the coiled region, is labeled 5 prime. The right end of the lower separated strand is labeled 5 prime, and the left end of the same strand, in the coiled region, is labeled 3 prime. A circle labeled Topoisomerase is wrapped around the coiled portion of the D N A close to the single stranded region on the right. A triangle labeled Helicase is positioned in the single stranded region at the point where the coiled strands are separating. A very short segment of R N A is bound to the far right end of the upper separated single strand of D N A. Figure 1. Model including molecules involved in DNA replication Which of the following correctly explains where DNA replication will begin on the strand oriented 5'→3', reading from left to right?
