The Ribosome

Interactions

Click a base on the mRNA ahead of the ribosome: it mutates, and by the codon table the change is silent, puts a different bead in the chain, or makes a new stop that cuts the protein short
Click a tRNA in the fluid: it is pushed into the A site, held against the codon, and thrown off if its anticodon does not pair
Click the ribosome: it stalls for five seconds, straining in small jolts, while tRNAs bounce off the closed A site
Move the pointer: it stirs the fluid around the drifting tRNAs
