The leading strand is elongated by the enzyme
SpletB. the leading strand is elongated by adding nucleotides to the 3’ end of the new strand, and the lagging strand is elongated by adding nucleotides to the 5’ end. C. the lagging strand is elongated continuously, whereas the leading strand is elongated in short fragments. SpletLeading and lagging strands. DNA 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 …
