Taking advantage of the addressability and programmability of DNA/DNA non-covalent interactions we report here the rational design of orthogonal DNA-based addressable tiles that self-assemble into polymer-like structures that can be reconfigured and reorganized by external inputs. The different tiles share the same 5-nucleotide sticky ends responsible for self-assembly but are rationally designed to contain a specific regulator-binding domain that can be orthogonally targeted by different DNA regulator strands (activators and inhibitors). We show that by sequentially adding specific activators and inhibitors it is possible to re-organize in a dynamic and reversible way the formed polymer-like structures to display well-defined distributions: homopolymers made of a single tile, random polymers in which different tiles are distributed randomly and block structures in which the tiles are organized in segments.

A novel type II restriction endonuclease UnbI was isolated from an unidentified psychrofilic bacterial strain from Antarctica. UnbI recognizes and cleaves the sequence 5'-GGNCC-3', producing 5 nucleotide long sticky ends. In this respect it differs from its neoschizomer Sau96I and all other restriction enzymes recognizing this sequence. UnbI has a relatively low temperature optimum of 15 degrees C to 20 degrees C and its activity is completely inhibited by inorganic phosphate.

Telomeres are associated with the ends of DNA double strands. The lengths of the telomeres are controlled by the telomerase enzyme. The shortening of the telomeres is known to relate to aging. In cancers, telomere lengths are abnormally short. Telomeres could act as buffers shielding the part of DNA coding for the proteins. For cancer cells, germ cells and stem cells the length of the telomeres is not varying. There is an analogy with microtubules, which are highly dynamical and carry a longitudinal electric field, whose strength correlates with the microtubule length. Could sticky ends generate a longitudinal field along DNA double strand with strength determined by the lengths of the sticky ends? In the standard picture the flux of the longitudinal electric field would be proportional to the difference of the negative charges associated with the sticky ends. In TGD framework, DNA strands are accompanied by the dark analog of DNA with codons realized as 3-proton units at magnetic flux tubes parallel to DNA strands and neutralizing the negative charge of ordinary DNA except at the sticky ends. This allows considering the possibility that opposite sticky ends carry opposite charges generating a longitudinal electric field along the magnetic flux tube associated with the system. DNA/Telomere bioelectric field could serve as a novel bioelectric marker to be used for prognostic and diagnostic purposes in researches of cancer, aging, surgery grafts and rejuvenation. We propsed that DNA bioelectric field can be used as a futuristic bioelectric marker of cancer, aging and death.
