What is one difference between dna and rna?

       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).

i dont know it at allnow im just getting points at this pint
