WebThe two DNA strands are separated during DNA replication and each parental strand serves as a template for the synthesis of a new daughter strand (Figure 1 (b)). After replication, … WebDNA is made differently on the two strands at a replication fork. One new strand, the leading strand, runs 5' to 3' towards the fork and is made continuously. The other, the lagging strand, runs 5' to 3' away from the fork and is made in small pieces called Okazaki fragments. log in cvr account
