During dna replication in e. coli, what is the role of dnaa? a. dnaa prevents reannealing of the separated dna strands so replication can occur. b. dnaa binds to and bends dna, hydrolyzing hydrogen bonds in the 13-mer region of oric and creating an open complex c. dnaa is a helicase that uses atp to hydrolyze hydrogen bonds and separate dna strands d. dnaa carries the helicase protein to the open region of dna where hydrolysis and strand separation will occur e. dnaa is a region of dna recognized by the replisome where replication is initiated
