In this 20-30 minutes, the bacterium has to duplicate its DNA, 4.5 million base pairs, produce every protein of its body another copy, assemble them into structures, and divide into two almost identical copies of individual bacterium. </p> |

In this plasmid, a RFP protein expression cassette (part number BBa_J004450) is inserted. The promoter has a lacI operon but in DH5alpha strain, its basal expression seems not under tight LacI control, probably due to weak expression levels of LacI in DH5alpha, and its huge copy numbers.</p> |
