Web11 de abr. de 2024 · These hairpins can snap together in specific ways. When a hairpin is closed, for example, two out of its three binding sites are unavailable. But, if a suitable strand of DNA docks with it, the hairpin springs open. A reaction between two DNA strands can also free up the exposed site on an attached hairpin, causing it to close once more. WebWith DNA in its "relaxed" state, a strand usually circles the axis of the double helix once every 10.4 base pairs, but if the DNA is twisted the strands become more tightly or more loosely wound. If the DNA is twisted in the direction of the helix, this is positive supercoiling, and the bases are held more tightly together.
