DNA is more stable than RNA. DNA is double-stranded and forms a double helix. RNA is usually single-stranded and folds back on itself to form stem-loop structures. RNA has 2' â¦ -OH group that can participate in intramolecular reactions, facilitating hydrolysis.
RNA contains ribose, while DNA contains deoxyribose, a similar sugar that contains one fewer oxygen molecule (de...oxy). Another difference is that DNA is double-stranded, while RNA is a single strand.Three of the nitrogenous bases are the same in the two types (adenine, cytosine, and guanine), but DNA contains thymine while RNA contains uracil. There are also functional differences.DNA is the blueprint for all proteins formed by the cells.NA contains ribose, while DNA contains deoxyribose, a similar sugar that contains one fewer oxygen molecule (de...oxy). Another difference is that DNA is double-stranded, while RNA is a single strand.
