The Salis Lab has recently discovered a new mechanism, called Ribosome Drafting, that controls a mRNA's translation rate. Learn more about it in our latest publication: Espah Borujeni and Salis. Translation Initiation is Controlled by RNA Folding Kinetics via a Ribosome Drafting Mechanism, Journal of the American Chemical Society, 2016

Promoter Sequence (optional)

Operon mRNA Sequence [?]
mRNA Sequence: enter the nucleotide sequence of an mRNA transcript, using A/G/C/T/U. (required)

Organism or (16S rRNA) [?]
Organism or 16S rRNA sequence: choose a bacterial species by typing in the first 3 letters of its name and selecting it from the list. Alternatively, you may enter the last 9 nucleotides of the 16S rRNA, using A/G/C/T/U.
