These ends thus remain unpaired and, over time, they may get progressively shorter as cells continue to divide. WebReplication cannot begin at any position in DNA by chance. There is a specific area known as the genesis of replication where replication starts. This is the location from which the replication starts. The discovery of this origin and subsequent unwinding of the two DNA strands signal the start of replication. location evg
