What is the difference between DNA and RNA? |
| Answer» \tDNA (Deoxyribonucleic acid)RNA (Ribonucleic acid)DefinitionIt 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.LocationIt is located in the nucleus of a cell and in the mitochondria.It is found in the cytoplasm, nucleus and in the ribosome.Sugar portionIt has 2-deoxyribose.It has Ribose.FunctionDNA 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 StructureThe 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.PropagationDNA 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 PairingThe 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).\t | |
