Why Do Origins of Replication in Various Bacteria Have Conserved

question 7

Multiple Choice

Why do origins of replication in various bacteria have conserved DNA consensus sequences?

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