Figure 1: Cartoon structures of the I·C and I·A base pairs. The increased width of the purine-purine I·A base pair requires the geometry of the anticodon to change, as the codon base is held in place ...

This image illustrates the chemical structure of a purine molecule, highlighting the numbering of the carbon and nitrogen atoms. The purine structure consists of a pyrimidine ring (positions 1 to 6) ...

While most enzymatic activity is conducted through chemical binding interactions between molecules, in some cases, the mere presence of an enzyme can affect intracellular functions. While exploring ...
