Answer:
N - glycosidic bond does not confer stability to the helical structure of DNA.
Explanation:
Phosphodiester bond is the linkage between carbon atoms in a sugar molecules of DNA and RNA.
H - bond is hydrogen bond that plays a major role in the stability of DNA as it is present between nucleotide molecules of DNA.
N - Glycosidic bond is the bond that binds carbohydrates to other molecules. So this bond does not play any role in the stability of DNA.
