Intramolecular base pairs can occur within single-stranded nucleic acids. This is particularly important in RNA molecules (e.g., transfer RNA), where Watson-Crick base pairs (guanine-cytosine and adenine-uracil) permit the formation of short double-stranded helices, and a wide variety of non-Watson-Crick interactions (e.g., G-U or A-A) allow RNAs to fold into a vast range of specific three-dimensional structures. In addition, base-pairing between transfer RNA (tRNA) and messenger RNA (mRNA) forms the basis for the molecular recognition events that result in the nucleotide sequence of mRNA becoming translated into the amino acid sequence of proteins via the genetic code.\n\nAnswer this question: what are the base pair rules for rna? Let's give stream of consciousness first:

The relevant information is: This is particularly important in RNA molecules (e.g., transfer RNA), where Watson-Crick base pairs (guanine-cytosine and adenine-uracil) permit the formation of short double-stranded helices, and a wide variety of non-Watson-Crick interactions (e.g., G-U or A-A) allow RNAs to fold into a vast range of specific three-dimensional structures.
So, the final answer is Watson - Crick base pairs ( guanine - cytosine and adenine - uracil ) permit the formation of short double - stranded helices , and a wide variety of non-Watson - Crick interactions ( e.g. , G-U or A-A ) allow RNAs to fold into a vast range of specific three - dimensional structures.
