RNA molecules form double stranded helices, just as do DNA molecules, by WatsonCrick 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。

Last Wednesday, Nature published excerpts of letter correspondences of Dr. Francis Crick, one half of the Nobel Prize-winning and double helix-discovering duo (James D.) Watson and Crick.
Whether we really understand DNA is debatable, but Francis Crick and James D. Watson published the first of many papers describing the double helix structure on this day in 1953.
