Definition
It is a long polymer. It has a deoxyribose and phosphate backbone having four distinct bases: thymine, adenine, cytosine and guanine.	Is a polymer with a ribose and phosphate backbone with four varying bases: uracil, cytosine, adenine and guanine.
Location
It is located in the nucleus of a cell and in the mitochondria.	It is found in the cytoplasm, nucleus and in the ribosome.
Sugar portion
It has 2-deoxyribose.	It has Ribose.
Function
DNA is functional is the transmission of genetic information. It forms as a media for long-term storage.	RNA is functional is the transmission of the genetic code that is necessary for the protein creation from the nucleus to the ribosome.
Predominant Structure
The DNA is a double-stranded molecule that has a long chain of nucleotides.	The RNA is a single-stranded molecule which has a shorter chain of nucleotides.
Propagation
DNA replicates on its own, it is self-replicating.	RNA does not replicate on its own. It is synthesized from DNA when required.
Nitrogenous Bases and Pairing
The base pairing is as follows: GC (Guanine pairs with Cytosine) A-T (Adenine pairs with Thymine).	The base pairing is as follows: GC (Guanine pairs with Cytosine) A-U (Adenine pairs with Uracil).
