Similarities and differences between rna and dna?

DNA and RNA both contain a cyclic nitrogenous base, a posphate group and a five-carbon sugar.  These are the base units of nucleotides which make up nucleic acids.  DNA contains the nitrogenous bases; adenine, thymine, cytosine and guanine wheresas RNA contains the bases; adenine, thymine, cytosine and urasil.  DNA codes for the nucleotides in an RNA molecule, whereas DNA codes for the amino acid sequence in a protein 

The main role of dna in the  cell is the long-term storage of information. it is often compared to a blueprint, since it contains the instructions to construct other components of the  cell, such as  proteins  and rna molecules.the main function of rna is to carry information of amino acid sequence from the genes to where  proteins  are assembled on  ribosomes  in the  cytoplasm. mark brainliest, my work is good.
