So this may be a really stupid question and the answer may be simple but I can't find it on the internet anywhere.

I know RNA has only a single polynucleotide, but I don't understand why it still has complimentary base pairs (e.g. uracil and adenine) when it doesn't pair to anything anyway?

RNA typically in the human body is a single polynucleotide.

RNA is able to form complimentary base pairs. An example of this is Protein synthesis when tRNA binds to mRNA.

The easiest explanation for why RNA doesn’t form two strands is the fact that the base pairs need to be exposed for protein synthesis and that RNA is also only used short term and needs to be easily attacked by enzymes to be able to break it down when enough of a protein has been made.

((((As a side note, you probably don’t need to know this, but RNA can be double stranded in some organisms like viruses (e.g. rota virus)))))
