Suggest a reason for the rather large energy excess available in the insertion of a deoxyribonucleotide into a growing DNA molecule. (About three times as much energy as is necessary is available in the reaction dNTP + DNAn → DNAn+1 + pyrophosphate.)

Favorable forward reaction

Explanation:

The very favorable forward reaction means that the reverse reaction is very unfavorable This strong forward reaction driving energy effectively inhibits the depolymerization reaction DNAn + pyrophosphate → dNTP + DNAn-1 A response that both absorb heat and decreases entropy will be non-unconstrained (positive ∆G) at all temperatures. A few responses, in any case, have a blend of ideal and horrible properties (discharging heat yet diminishing entropy, or retaining heat yet expanding entropy). The ∆G and suddenness of these responses will rely upon the temperature
