Currently, most of the RNAs used in lab research are prepared by in vitro transcription or chemical synthesis, which can be costly. In vivo expression in bacterial cells is another approach to RNA preparation that allows large scale production at a lower cost. However, there are some obstacles in bacterial expression, including RNA degradation in host cell, as well as RNA extraction and purification. tRNA and 5S RNA have been reported as scaffolds to circumvent the degradation problem. These scaffolds can not only make the RNA product survive in the cell but also increase the stability after extraction.
