Initiator proteins break hydrogen bonds separating short length of DNA, AT base pairs are held together by fewer hydrogen bonds than GC pair. Thus AT pairs are easier to pull apart, At rich regions are typically found in the replication origins. Replication origins are site at which DNA is first opened.
