What is the relationship between DNA and RNA

RNA is somewhat similar to DNA; they both are nucleic acids of nitrogen-containing bases joined by sugar-phosphate backbone. How ever structural and functional differences distinguish RNA from DNA. Structurally, RNA is a single-stranded where as DNA is double stranded. DNA has Thymine, where as RNA has Uracil. RNA nucleotides include sugar ribose, rather than the Deoxyribose that is part of DNA. Functionally, DNA maintains the protein-encoding information, whereas RNA uses the information to enable the cell to synthesize the particular protein.

What is the relation between RNA and DNA?
RNA and DNA are structurally similar, in that they have sugar-phosphate backbones and nitrogenous bases.
However they differ in that RNA has ribose sugars whereas DNA has deoxyribose; they also have a different complement of bases, in that while they both have A, G and C, DNA has T whereas RNA has U.
DNA is typically found in the familiar double-helical structure, with two anti-parallel strands, whereas RNA is found in a much greater variety of structures.
Leaving aside viruses, DNA is typically used for the long-term storage (and inheritance) of genetic information; RNA provides a much wider range of functions but tends to be shorter-lived. For example, it forms a key part of the structure of the ribosome (ribosomal RNA); it acts as “adaptors” in translation (transfer RNA); and it forms a temporary copy of genes that are translated into proteins (messenger RNA). It serves other functions, too, not all of which are well understood yet.
