WebDec 30, 2024 · There is only one origin in prokaryotes (in E. coli, oriC) and it is characterized by arrays of repeated sequences. These sequences wrap around a DNA-binding protein, and in doing so, exert pressure on the H-bonds between the strands of DNA, and the chromosome begins to unzip in an AT-rich area wrapped around this protein. WebAug 22, 2024 · Origins of replication (Ori C) are found in abundance in eukaryotic cells, and replication can proceed in either way. Replicating DNA is a semi-conservative process that creates a new copy of the DNA molecule to join the original strand. During the S phase, it occurs at numerous chromosomal origins.
