SIDE · PDB 1EHZ

The suspect, from its real atomic coordinates. Drag to turn it. Height chart in nanometers, a line every nanometer. About a thousand, stacked, would match the width of the yeast cell it lives in.

Rap sheet

Answers to
tRNA. Comes when called, but only by UUU or UUC.
Height
7.3 nm, standing on one leg.

Build
L-shaped: two arms of about 7 nm, at right angles.
Color
None to speak of. One letter glows violet-blue.
Marks
A three-letter tattoo, GAA, at the tip of one arm.

Last seen
A 5 mL tube marked YEAST in the fridge at HQ.
3,000,000

of them in every yeast cell, give or take, and a packet
of baker’s yeast holds about 200 billion cells. You’ve never seen one.
