The DNA is made up of two pieces of nucleotide chains, which is double helix structure with complementary pairing of the bases and winding each other.
沃森一起为脱氧核糖核酸的分子结构提出了双螺旋这种 螺旋模型。
RNA molecules form double stranded helices, just as do DNA molecules, by Watson Crick pairing of nucleotides on the two complementary strands of the helix.
RNA分子能像DNA分子那样形成双链螺旋，通过沃森·克里克配对，两个螺旋的核苷链互补。
Without specific base pairing, the replication enzymes cannot specify a complementary strand, and gaps are left after the passing of a replication fork.
失去特定的碱基互补配对，复制酶系就不能合成模板链的互补链，而是在经过复制叉后留下一个裂口。
