You cool it down to room temperature, and as you do, what happens is those short strands, they do the following thing: each one of them binds that long strand in one place, and then has a second half that binds that long strand in a distant place, and brings those two parts of the long strand close together so that they stick together.
Ohladite do sobne temperature, a za vrijeme hlađenja oni kratki nizovi čine sljedeću stvar: svaki od njih veže onaj dugački niz na jednom mjestu, a tada druga polovica veže taj dugački niz na udaljenom mjestu te ih približi jedan drugome i tako ih veže.
