abstract：:Long noncoding RNAs (lncRNAs) do not code for proteins but function as RNAs. Because the functions of an RNA rely on either its sequence or secondary structure, lncRNAs should be folded at least as strongly as messenger RNAs (mRNAs), which serve as messengers for translation and are generally thought to lack secondary...
