In DNA phosphodiester bond is formed between what?

A. sugar और phosphate groups / Sugar and phosphate groups

Step 1: Identify nucleic acid backbone. Step 2: In DNA strand sugar and phosphate groups join by phosphodiester bonds to form backbone. Step 3: Remember DNA backbone equals sugar phosphate chain.

Step 1: nucleic acid backbone पहचानें। Step 2: DNA strand में sugar और phosphate groups phosphodiester bonds से जुड़कर backbone बनाते हैं। Step 3: DNA backbone equals sugar phosphate chain याद रखें।
