Which of the following statements about polynucleotide formation is correct? As a polymer, DNA is not metastable but fully stable DNA forms through a spontaneous, single step dehydration to form the sugar-phosphat backbone Pyrophosphate hydrolysis is a key step driving nucleoside polymerization The overall equation for DNA formation is: DNAN+NTP DNAN+1+H₂O Nucleotide diphosphates are the building blocks of polynucleotides
