If SSB is not present during DNA replication, what would you expect to see?
A) The replisome complex would not assemble on the oriC region.
B) The DNA cannot bend, so hydrogen bonds in the 13-mer region of oriC remain intact.
C) Helicase activity is inhibited, so DNA strands cannot be separated.
D) SSB carries the helicase protein to the open region of DNA, so hydrolysis and strand separation will not occur.
E) SSB prevents reannealing of the separated strands, so strands would quickly reanneal and DNA replication cannot proceed.
