Question

what is one difference between dna and rna?

Answer 1

DNA is a double stranded nucleic acid which forms a double-helix structure made up of two chains of nucleotides, quite similar to that of a twisty ladder.  RNA is only made up of a single strand of amino acids and therefore only forms a single stranded helix structure. 

Answer 2

Answer:

       There are some main differences between DNA and RNA, the first one is quite simple, DNA is made out of a double ribbon, and RNA is made out of a single one. But this is not the only difference, and not even the main one. The main difference is at their content, DNA includes some nucleotides , they are cytosine (C), thymine (T), adenine (A), guanine (G), but on RNA it's a little bit different. Instead of a thymine, there's a new nucleotide called uracil (U). By that information we can rearrange the base pairs, in DNA it's (A-T) and (C-G), but in RNA it's (A-U) and (C-G).
