This part encodes a Promoter.RNA composite part
Sometimes we make basic parts contain more than just a primitive element if there is reason to believe that some natural non-biobrick composition might be important for its activity. This is one of those instances. The part encodes a native promoter and a non-coding RNA element, but no terminator.
Parts containing transcriptionally-competent constructs are often toxic to E. coli, so you may have some difficulty making this part. Make careful note in your notebook about the size distribution of colonies you get on your plates and the ratio of red to white colonies.
