Answer 2

According to watson and Crick model of DNA, each DNA molecule is a double stranded structure.
Both strands twist around an imaginary axis to form ladder shaped structure.
Longer arms are made of sugar and phosphate but the transvers arms are made of nitrogenous bases.
Phosphate molecule attached with either 3rd or 5th c-atom of sugar by phosphoester bond.

hope this is helpful! :)
