In a purine nucleotide in DNA, the positions that have the potential to form hydrogen bonding but are not involved in Watson-Crick base pairing are the N7 and N9 positions of the purine ring. These positions have lone pairs of electrons that can participate in hydrogen bonding interactions with other molecules or functional groups. However, in the context of DNA, these positions do not typically participate in the formation of base pairs with complementary nucleotides. Instead, they may be involved in other types of interactions, such as stacking interactions with adjacent nucleotides or interactions with proteins or other molecules in the cellular environment.
