The sugar in RNA is ribose, not deoxyribose
|
|
|
DNA is double-stranded
|
|
|
RNA has thymine, DNA has uracil
|
|
|
RNA is single-stranded
|
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 thing that is not a difference is C. So DNA and RNA are both made up of nucleotides. Nucleotides. It’s something like this as a phosphate group.
Detailed explanation-3: -RNA contains uracil, while DNA contains thymine. Explanation: RNA is different than DNA in that it 1) is single stranded (DNA is double stranded), 2) contains uracil (DNA contains thymine instead), and 3) contains a ribose sugar (DNA contains a deoxyribose sugar).
Detailed explanation-4: -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-5: -Uracil (U) is one of the four nucleotide bases in RNA, with the other three being adenine (A), cytosine (C) and guanine (G). In RNA, uracil pairs with adenine. In a DNA molecule, the nucleotide thymine (T) is used in place of uracil.
