Why is there a leading strand and a lagging strand during replication?
a.DNA helicase can only unwind one strand at a time
b.there are not enough single strand stabilizing proteins for both strands
c.DNA polymerase can only synthesize from 5’ to 3’
d.it takes time for the polymerase to proof read
e.telomerase can only synthesize from 5’ to 3’
C is your correct answer but it is a crucial one for understanding the concept of how DNA replication occurs. I would watch something like http://www.youtube.com/watch?v=teV62zrm2P0 to better understand the whole process and how it fits together.
