    "abstract": "We predict a novel temperature-driven phase transition of DNA below the\nmelting transition. The additional, intermediate phase exists for repetitive\nsequences, when the two strands have different lengths. In this phase, the\nexcess bases of the longer strand are completely absorbed as bulge loops inside\nthe helical region. When the temperature is lowered, the excess bases desorb\ninto overhanging ends, resulting in a contour length change. This continuous\ntransition is in many aspects analogous to Bose Einstein condensation. Weak\nsequence disorder renders the transition discontinuous.",
