#Unit 3. Fundamental Processes

The charging of a tRNA with its cognate amino acid is a remarkably accurate process.

Experimental measurements indicate, for example, that at equal concentrations of isoleucine and valine, IleRS transfers ∼40,000 isoleucines to tRNAIle for every valine it so transfers.

#Unit 1. Molecules and their Interaction Relevant to Biology

Intrinsically disordered proteins lack a hydrophobic core, and have high densities of charged amino acid residues such as Lys, Arg, and Glu. Pro residues are also prominent, as they tend to disrupt ordered structures.
