Abstract:
DNA extracted from Allium Cepa (white onion) has been exposed to a variety of external thermodynamic parameters including: elevated temperature; low molar concentration salt solution; and very high simulated gravity. Results show that the actions of a dilute NaCl solution and of elevated temperature (to 65C) tend to unwind the double helix. This process is useful in nano-fabricating DNA polyhedra, particularly tetrahedra, in order to contain a trapped protein for microbiological applications such as anti-viral medication. Our results also show how the cellular structure of DNA changes its character and topology in response to extreme hyper gravity.
