<span><span>The first step in DNA replication is to ‘unzip’ the double helix structure of the <span>DNA?</span> molecule.</span><span>This is carried out by an <span>enzyme?</span> called helicase which breaks the <span>hydrogen bonds?</span> holding the <span>complementary?</span> <span>bases?</span> of DNA together (A with T, C with G).</span>The separation of the two single strands of DNA creates a ‘Y’ shape called a replication ‘fork’. The two separated strands will act as templates for making the new strands of DNA.<span>One of the strands is oriented in the 3’ to 5’ direction (towards the replication fork), this is the <span>leading strand?</span>. The other strand is oriented in the 5’ to 3’ direction (away from the replication fork), this is the <span>lagging strand?</span>. As a result of their different orientations, the two strands are replicated differently:</span></span>
