a: Dna replication leading strand ~
b: zipper

What: "That leading strand is like a zipper, it is always replicating. The lagging strand is kind of like lego pieces being connected. Since The leading strand blocks part of the lagging strand, the lagging strand has less nucleotides than a leading strand, making it shorter."
