The simple summary is that DNA makes RNA, and then RNA makes proteins. DNA, RNA and proteins all consist of a repeating structure of related building blocks (nucleotides in the case of DNA and RNA, amino acids in the case of proteins). In general, they are all unbranched polymers, and so can be represented in the form of a string.
3. DNA has deoxyribose; RNA has ribose. 4. DNA stays in the nucleus; RNA can goes out of the nucleus. Same: 1. DNA and RNA are both made of blocks called nucleotides, consisting of sugar/phosphate/nitrogen base. 2. DNA and RNA share the bases adenine, cytosine, guanine. The phosphates are the same, of course.
