During log-phase growth, e. coli can divide once every 20 minutes. the e. coli chromosome is about 4,600,000 base pairs long. the single origin of replication provides two replication forks, and each of the associated dna polymerase synthesizes about 750 base pairs per second. how long will it take, in minutes, to duplicate the e. coli chromosome?
