|
DNA is an amino acid and RNA is a nucleic acid.
|
|
|
DNA contains phosphate and RNA contains potassium.
|
|
|
DNA has a nitrogenous base and RNA has a carbon base.
|
|
|
DNA contains deoxyribose sugar and RNA contains ribose sugar.
|
Detailed explanation-1: -There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.
Detailed explanation-2: -The pentose sugar in DNA is called deoxyribose, and in RNA, the sugar is ribose. The difference between the sugars is the presence of the hydroxyl group on the 2’ carbon of the ribose and its absence on the 2’ carbon of the deoxyribose.
Detailed explanation-3: -So, the three main structural differences between RNA and DNA are as follows: RNA is single-stranded while DNA is double-stranded. RNA contains uracil while DNA contains thymine. RNA has the sugar ribose while DNA has the sugar deoxyribose.
Detailed explanation-4: -Summary of Differences Between DNA and RNA DNA is a double-stranded molecule, while RNA is a single-stranded molecule. DNA is stable under alkaline conditions, while RNA is not stable. DNA and RNA perform different functions in humans.
Detailed explanation-5: -DNA contains deoxyribose as the sugar component and RNA contains the sugar ribose.
