Write one structural difference between DNA and RNA.
Show Hint
Solution and Explanation
Step 1: Structure of DNA DNA contains:
• Deoxyribose sugar
• Bases A, G, C and T
• Usually double-stranded structure
Step 2: Structure of RNA RNA contains:
• Ribose sugar
• Bases A, G, C and U
• Usually single-stranded structure
One structural difference The sugar present in DNA is deoxyribose, whereas the sugar present in RNA is ribose. \[ \boxed{ \text{DNA contains deoxyribose sugar whereas RNA contains ribose sugar.} } \]

(ii) Secondary and tertiary amines
(iii) Ethylamine and aniline
(iv) Aniline and benzylamine
(v) Aniline and N-methylanilineAccount for the following:
