Which of the following statement about DNA replication in E.coli is correct? A)Single- stranded binding proteins are only required on the leading strand. B)Only the lagging strand needs to be primed. C)There are two molecules of DNA polymerase III per replication fork. D)DNA polymerase I follows closely behind DNA helicase in the replication fork. E)There are two molecules of DNA helicase per replication fork.

There are two molecules of DNA polymerase III per replication fork in E.coli. DNA polymerase III is responsible for the majority of DNA synthesis during replication.

Note: A, B, D, and E are incorrect statements. Single-stranded binding proteins are required on both the leading and lagging strands, both strands need to be primed, DNA polymerase I is involved in removing RNA primers and filling in gaps but does not follow helicase closely, and there is only one molecule of DNA helicase per replication fork.
