E. coli Replication Origin. The E. coli replication origin oriC is an â240-bp DNA segment present at the start site for replication of E. coli chromosomal DNA. Plasmids or any other circular DNA containing oriC are capable of independent and controlled replication in E. coli cells.. coli Replication Origin.

dna replication e coli what problems does dna structure cause for its own replication dna is a stable molecule composed of two linear chains these chains are attached to one another through hydrogen bonds between complimentary bases the double chain then forms a helical coil the bonding between the chains and the coil keep the base sequence stable and allow the dna molecule to replicate itself however replication requires the uncoiling and separation of the two strands in the region where new dna is being actively synthesized a series of molecules are required to separate the strands and stabilize the coils in addition to dna polymerase and the associated molecules that make new dna
