FAQ

Will a molecular biologist actually appreciate this?

Yes. The cloverleaf is how tRNA gets taught and how most molecular biologists carry it in their head: four arms, three loops, the anticodon at the bottom, the acceptor stem with the CCA tail at the top. Drawing it on a napkin is something they have done many times. Wearing it works as a quiet version of the same gesture.

Why does tRNA have two recognisably different ends?

The two ends do separate jobs. The anticodon loop at the bottom of the cloverleaf reads three bases of mRNA, deciding which codon this tRNA matches. The 3' CCA tail at the top of the acceptor stem carries the amino acid that gets added to the growing protein. In three dimensions the molecule folds into an L-shape that keeps the two functional ends roughly 70 angstroms apart, which is the distance the ribosome needs between codon recognition and peptide bond formation. The fold is what makes the genetic code work as an adapter system.

What size is the pendant and what does it ship with?

The pendant is 33 mm tall, sized so the four arms of the cloverleaf and the three loops are all readable at a glance. It ships on a 45 cm sterling silver chain (1.8 mm width, lobster clasp) with a 5 cm extender. Free worldwide DHL Express shipping in 1-5 business days, all import duties covered, in a ready-to-gift jewelry box.

Why tRNA, when there are other RNA pieces in the catalog?

RNA covers a lot of ground. Messenger RNA carries the message, ribosomal RNA does the catalysis, microRNAs regulate, and several others handle splicing or interference. The tRNA is the adapter: the only RNA whose entire job is to read three letters of one molecule and deliver one specific amino acid to the right address. It is the moment where the genetic code stops being information and becomes chemistry.
