Quizplus · Accepted Answer

Polynucleotide synthesis involves the formation of phosphodiester bonds between nucleotides, which release pyrophosphate (PPi) as a byproduct. The hydrolysis of PPi by pyrophosphatase makes the overall reaction exergonic and drives the synthesis of polynucleotides forward. This is a key driving force for polynucleotide synthesis. The options A, C, and D are incorrect because polynucleotides are generally stable, the hydrolysis of nucleoside triphosphates is not the only driving force for polynucleotide synthesis, and polynucleotides are susceptible to hydrolysis under certain conditions.
