RNA is single stranded
|
|
|
RNA does not have the base Thymine
|
|
|
RNA has the base Uracil
|
|
|
All of these are correct
|
Detailed explanation-1: -DNA differs from RNA in the nature of sugar and pyrimidines. DNA has deoxyribose sugar, while RNA has ribose sugar. Among pyrimidines, DNA has thymine and cytosine, while RNA has uracil and cytosine.
Detailed explanation-2: -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-3: -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-4: -Answer and Explanation: The correct answer is: (c) DNA contains alternating sugar-phosphate molecules whereas RNA does not contain sugars.
Detailed explanation-5: -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.
