The overall reaction rate for the bacterial RNA polymerase can be as fast as 40–50 nucleotides/ second at 37°C for most transcripts; this is about the same as the rate of translation (15 amino acids/sec), but much slower than the rate of DNA replication (800 bp/sec).

ORC was first found in S. cerevisiae (where it may be called scORC),but similar complexes have now been characterized in Schizosaccharomyces pombe (spORC), Drosophila (DmORC ), and Xenopus (XIORC).
