| RNA contains ribose sugars and the nucleic acid uracil. DNA contains deoxyribose and the nucleic acids thymine. Both contain adenine, guanine and cytosine as bases. In RNA the uracil replaces the thymine found in DNA, so they both still have a phosphate sugar backbone and four base pairs in a helitcal structure. DNA is a double-stranded molecule in a helitical (spiral) shape. RNA is a single stranded molecule in a helitical form. RNA is also usually shorter than DNA. |
