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.
Basically, DNA is â¦ the blueprint that will ultimately decide which proteins will be made. Proteins are made up of sequences of amino acids. If two organisms have similar amino acid sequences, that means that they must have similar DNA that told the cells to make those amino acid sequences.
