Answer 1

\[\begin{array}{|c|c|c|} \hline Feature & DNA (Deoxyribonucleic Acid) & RNA (Ribonucleic Acid) \\ \hline \text{Sugar} & \text{Contains deoxyribose sugar} & \text{Contains ribose sugar} \\ \hline \text{Structure} & \text{Double-stranded helix} & \text{Single-stranded} \\ \hline \text{Nitrogen Base} & \text{Thymine (T) present} & \text{Uracil (U) replaces Thymine} \\ \hline \end{array}\]Final Answer: \[ \boxed{\text{DNA differs from RNA in sugar, strand structure, and nitrogen bases.}} \]
