For two complementary strands of nucleotides, the free energy is minimized when they pair up to form a double helix. 就兩股互補的核苷酸分子而言，配對形成一條雙股螺旋時(shí)的自由能會(huì )最低。
It provided strong evidence of the structure of D-N-A as a double helix. 它為脫氧核糖核酸結構呈雙螺旋線(xiàn)提供了有力證據。
Many of the databases along the double helix were shut down, closed, so that you began to function with very little data. 許多數據庫是順著(zhù)雙螺旋線(xiàn)停止運行，關(guān)閉，讓你們開(kāi)始運行很少的數據。
