Why do origins of replication in various bacteria have conserved DNA consensus sequences?
◦ Consensus sequences are found throughout bacterial genomes and so would be found at the origin as well.
◦ The consensus sequence allows the origin to wrap into a circle and recruit replication initiation proteins.
◦ It is more efficient to use the same sequence multiple times in different genomes than to change it.
◦ Fewer mutations in the DNA occur at the very beginning of replication at the origin, hence why they are conserved as consensus sequences.
◦ Origins need to be recognized by replication initiation proteins to open up their AT-rich regions.
