Best Answer: 4) RNA contains ribose, DNA does not. DNA contain the deoxyribose sugar. Other differences may include; DNA is double stranded while RNA is single stranded. DNA contain the base thymine while RNA contain the base Uracil in place of thymine.
(note that the carbons in deoxyribose are numbered). 2. DNA is double stranded (ds), meaning there are two of the above strands together. Try to assemble a ds DNA molecule with sugar phosphate backbones on the outside, and nitrogen bases on the inside.here are two sugars found in nucleic acids; ribose is found in RNA (r ibo n ucleic a cid) and deoxyribose in DNA. Deoxyribose refers to the fact that one of the hydroxyl (OH) groups is missing from this sugar. Examine the two sugars below. Identify which is ribose and which is deoxyribose.
