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。

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.
