Compare and contrast the features of eukaryotic DNA and RNA

Both DNA and RNA a nucleic acids, made up of nucleotides, that encode genetic information. A nucleotide is a molecule composed of phosphate, sugar and a base, and these nucleotides bind to one another to form a strand, much like a chain. In the case of DNA, the sugar present is called deoxyribose and the bases are adenine (A), thymine (T), guanine (G) and cytosine (C), and these bases on one strand are able to form bonds with complementary bases on another strand (A always binds T, and G always binds C), thus forming a double stranded helix. DNA is found in the nucleus of the cell. RNA on the other hand contains the sugar ribose, and the base uracil (U) instead of T (all other bases and their complementary pairings are otherwise the same). Though the bases of RNA are able to bind to one another like those of DNA, RNA exists almost always as single strands. These are found in the cytoplasm of the cell.
