7. Which of the following features are common to essentially all (prokaryotic, eukaryotic, viral) replication origins?
(A) Origin sequences have inverted repeats that form stable secondary structures for assembly of the replication apparatus.
(B) Origins are unique DNA segments that often contain multiple short repeated sequences involved in binding to replication proteins.
(C) DNA polymerase is able to recognize promoter-like sequences at the replication origins.
(D) The origin-flanking sequences are G-C rich to stabilize the DNA-protein initiation complex.
