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.
DNA is a doubled stranded structure, while RNA is a single stranded structure. RNA contains the sugar ribose, while DNA contains the sugar deoxyribose. RNA can have 4 nucleoti â¦ des: cytosine, guanine, uracil, and adenine. DNA can have all these nucleotides except for uracil, which is replaced by thymine.ere are some major â¦ differences between RNA and DNA: With the exception of a few viruses, RNA is a single-stranded molecule while DNA is double-stranded. The two DNA chains are connected by hydrogen bonds between nitrogenous bases. DNA can is replicated during cell division; RNA is not.
