The Template-And-Nutrient Principle The core principle governing how DNA polymerase adds nucleotides is strict complementarity. This oxygen atom attacks the alpha-phosphate of the incoming dNTP, displacing the beta and gamma phosphates as pyrophosphate.
How Hydrogen Bonds Guide Accurate Nucleotide Selection
The result is the formation of a phosphodiester bond that links the new nucleotide to the chain. The structural rearrangement effectively "locks" the correct base in place before the bond is finalized.
The Chemical Mechanism of Bond Formation The actual chemistry involves a nucleophilic attack by the 3' hydroxyl group of the growing chain. The process is a dynamic interaction between the protein, the DNA substrate, and the incoming nucleoside triphosphate.
How Hydrogen Bonds Guide Accurate Nucleotide Selection
DNA polymerase interacts with sliding clamps and other accessory proteins that tether it to the template. The correct nucleotide is then reloaded, allowing synthesis to continue without propagating the error.
