Abstract
rClone Red is a low-cost and student-friendly research tool that has been used successfully in undergraduate teaching laboratories. It enables students to perform original research within the financial and time constraints of a typical undergraduate environment. Students can strengthen their understanding of the initiation of bacterial translation by cloning ribosomal binding sites of their own design and using a red fluorescent protein reporter to measure translation efficiency. Online microbial genome sequences and the mFold website enable students to explore homologous rRNA gene sequences and RNA folding, respectively. In this report, we described how students in a genetics course who were given the opportunity to use rClone Red demonstrated significant learning gains on 16 of 20 concepts, and made original discoveries about the function of ribosome binding sites. By combining the highly successful cloning method of golden gate assembly with the dual reporter proteins of green fluorescent protein and red fluorescent protein, rClone Red enables novice undergraduates to make new discoveries about the mechanisms of translational initiation, while learning the core concepts of genetic information flow in bacteria.
