You work in a famous biotech. The board of directors wants you to develop a new way to manipulate bacterial cells based on gene regulation. Describe in detail two ways to do that.  Some hint keywords (you won’t need all words): regulatory transcription factors, repressors, activators, small effector molecules, inducers, repressors, attenuation, translational repressors, antisense RNA, feedback inhibition, posttranslational regulation, riboswitches, RNA thermometers.  

Eukaryotic Origins of Replication can be based on sequence, such as the ARS elements (Autonomously Replicating Sequence), or on structure, such as G-rich sequences, or G4 motifs, that form a G-quadruplex.
