DNA Helicase begins splitting the DNA at the origin of replication, which is atan AT bond. AT bonds are only doublebonds, whereas CG bonds are triple bonds. Helicase breaks a double bondeasier, so it looks for an AT bond.

3’ Since DNA replication happens in a 3’to 5’ pattern, the right strand, or the lagging strand, replicates a new strand after the leading strand. However, DNAcan’t replicate this way, so DNA Primaseis added to temporarily make it a 5’ to3’ strand.
