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.
Most enzymes are proteins, but RNA molecules can be enzymes too. The ribosome is not only complex, but it is also the most important part of the biological cell, along with the necessary information needed to make proteins (encoded in DNA or RNA). Ribosomes make proteins and proteins make cells. Ribosomes may well
