|
RNA is different from DNA, because RNA:
|
Is a single strand
|
|
Contains the sugar ribose
|
|
Replaces Thymine for Uracil
|
|
All of these answers
|
Explanation:
Detailed explanation-1: -DNA is a double-stranded molecule that has a long chain of nucleotides. RNA is a single-stranded molecule which has a shorter chain of nucleotides. DNA replicates on its own, it is self-replicating. RNA does not replicate on its own.
Detailed explanation-2: -RNAs also contain nitrogenous bases linked to sugar and phosphate like DNA, but RNAs contain ribose sugar and Uracil instead of deoxyribose sugar and Thymine in DNA.
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.
