DNA Topologyles, which contain all the information on the structure of living organisms, consist of two polymer chains attached to one another by weak, noncovalent interactions. These chains form a double helix in which γo = 10 monomer links (base pairs) occur per turn. Actual DNAs contain from several thousand作者: 倔強(qiáng)不能 時間: 2025-3-22 08:19
