The new DNA synthesized on a leading strand is done in a continuous manner without breaks. The leading strand of DNA does not require an RNA primer. On the other hand, the lagging strand is positioned in 3’ to 5’ direction, and it is opposite to the direction of the replic...Read More

This is synthesized continuously which means that you will find no breaks in between the strands. Lagging DNA strands is the one that is synthesized in the opposite direction. It grows away from the replication fork....Read More
