Solution and Explanation
Step 1: Structure of DNA and RNA.
DNA (Deoxyribonucleic Acid) and RNA (Ribonucleic Acid) are nucleic acids but differ in sugar, bases, structure, and function.
Step 2: Key differences.
\begin{tabular}{|c|c|c|} \hline Feature &
DNA &
RNA
\hline Sugar & Deoxyribose & Ribose
\hline Bases & A, T, G, C & A, U, G, C (U replaces T)
\hline Strands & Double-stranded helix & Single-stranded
\hline Function & Genetic material, stores information & Protein synthesis (mRNA, tRNA, rRNA)
\hline Location & Mostly in nucleus & Nucleus and cytoplasm
\hline \end{tabular} Conclusion:
DNA stores and transmits genetic information, while RNA helps in protein synthesis and gene expression.
