During DNA replication Both leading and lagging daughter DNA strands are synthesized in the 5β to 3β direction. The leading strand is synthesized in the 3β to 5β direction but the lagging strand is synthesized 5β to 3β. The leading strand is synthesized in the 5β to 3β direction but the lagging strand is synthesized 3β to 5β. Both leading and lagging daughter DNA strands are synthesized in the 3β to 5β direction.

Why does DNA replication have a leading and lagging strand? DNA is antiparallel in structure, so has replication built going both towards and away from the direction of the replication fork The lagging strand is made twice as fast as the leading strand during replication The leading strand is synthesized discontinuously in the 5' 3' direction, while the lagging strand is synthesized continuously in the 5' 3' direction DNA is antiparallel in structure, so has DNA being added from the 5' end and the 3' end, resulting in the two strands

During DNA replication, the leading and the lagging strands differ in that the leading strand is synthesized towards the replication fork, while the lagging strand is synthesized in the opposite direction, away from the replication fork. The leading strand is synthesized by adding nucleotides to the 3' end of the growing strand, while the lagging strand is synthesized by adding nucleotides to the 5' end. The leading strand is synthesized continuously, whereas the lagging strand is synthesized in short fragments that are ultimately stitched together. Both A and B.

Q4.7. In DNA replication, what is the difference between the leading and lagging strands? In the leading strand, DNA is synthesized 5'β3', while in the lagging strand it is synthesized 3'β5'. The leading strand is composed of DNA only, while the lagging strand is composed of both RNA and DNA. After extension, the leading strand is continuous, while the lagging strand is composed of disconnected fragments. The leading strand is synthesized only by DNA polymerase III, while the lagging strand is synthesized only by DNA polymerase I.
