the helical structure

the identity of the bases

|
|
the identity of the sugar
|
|
|
the sugar to phosphate linkages
|
Detailed explanation-1: -The linkage of phosphate groups with the nucleotides of both RNA and DNA is the same. The nitrogen bases like adenine, guanine, and cytosine are the same in both of the nucleic acids but the nitrogen base thymine which is present in DNA will get replaced by uracil in RNA.
Detailed explanation-2: -Sugar. Both DNA and RNA are built with a sugar backbone, but whereas the sugar in DNA is called deoxyribose (left in image), the sugar in RNA is called simply ribose (right in image).
Detailed explanation-3: -Both DNA and RNA are made up of a pentose sugar, phosphate group and a base.
Detailed explanation-4: -DNA and RNA are composed of nucleotides that are linked to one another in a chain by chemical bonds, called ester bonds, between the sugar base of one nucleotide and the phosphate group of the adjacent nucleotide.
Detailed explanation-5: -DNA contains phosphates, while RNA does not. RNA contains uracil, while DNA contains thymine.
