6. Molecular formal inversion - A.

DNA. As soon as DNA was established as the Thread of Life, a formal inversion principle was firmly in place. The two strands of the sugar-phosphate backbone of DNA run in inverse chemical directions, and it is this locking nature of the arrangement that provides the relative genetic stability that DNA brings to the living world. This feature of DNA might be regarded as the Fundamental Formal Inversion, even though it is not as yet clear how (or if) this particular kind of formal inversion is translated into the others that will be mentioned.
