In the process of transcription, what secondary structure of RNA allows for the complementary base pairing of nucleotides?

Core Concept

During transcription, the secondary structure of RNA, including hairpin loops, allows for the complementary base pairing of nucleotides. This allows for the correct base pairing of nucleotides during transcription. Amino acid bonds are involved in protein synthesis, the sugar-phosphate backbone is the structural component of nucleic acids, and the double helix structure is characteristic of DNA.
