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。

From a distance, these building blocks look very similar, so every piece of DNA you look at has the same overall shape—the famous Watson-CrickDoubleHelix.
从远处看，这些基本成分看上去极为相似，因此 DNA 的每一部分的基本形状都是相同的 — 著名的沃森克里克双螺旋结构。

Last Wednesday, Nature published excerpts of letter correspondences of Dr. Francis Crick, one half of the Nobel Prize-winning and doublehelix-discovering duo (James D.) Watson and Crick.
