Arabinose Operon Pglo, The pGLO plasmid contains an origin or replication, a selectable marker, and the gene for Green Fluorescent Protein (GFP). The plasmid also contains a gene for the arabinose C protein, which is a In the presence of arabinose, AraC changes shape, no longer blocks PBAD, and instead recruits RNA polymerase to transcribe GFP, leading to green glowing bacteria. In the pGLO plasmid DNA, some of the genes . This process was demonstrated using When the arabinose runs out, the genes are turned off again. Arabinose initiates transcription of these genes by promoting the binding of RNA polymerase. Transcription of these genes by RNA polymerase occurs from a common promoter site called PBAD. Other features on pGLO, like Find a lab station, be familiar with what and where the materials are! Ask questions as needed! The DNA code of the pGLO plasmid has been engineered to incorporate aspects of the arabinose operon. The araBAD operon encodes three proteins needed for the degradation of L-arabinose. The pGLO plasmid was made famous by researchers in France who used it to produce a green fluorescent rabbit named Alba. Here’s how that switch actually works. The genes which code for break down of arabinose, araB, A and D, have been replaced by In this project, the central dogma was demonstrated, showing replication, transcription, reverse transcription, translation, and gene expression. Arabinose acts as a molecular switch in pGLO bacteria, turning on GFP so cells glow green.
