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.
Genes are composed of a sequence of nucleotides in a DNA molecule that specify the structure of a protein or RNA molecule.   Genes consist of DNA (deoxyribonucleic acid) â¦ , DNA contains the information that determines the structure of proteins. RNA (ribonucleic acid) is structurally related tp DNA.
