similarities in structure of dna and rna
Answer by Ridens. Confidence votes 2.8K. They are both nucleic acids. Regarding structure, DNA and RNA are similar because they are both built of nucleotides, structures consisting of one nucleobase, a sugar (ribose or deoxyribose respectively) and a phosphate group.For both of them, their function is mainly containing information in the form of code, using 4 different bases.nswer by Ridens.
