what bases bond together in rna
A base pair is made of two nucleotides. The nucleotides, located on opposite strands of DNA or RNA, are drawn to each other in a hydrogen bond. These bonds are what hold the strand together in a double helix formation. The double structure is a redundancy that acts as a backup system to store genetic information. Base pairs facilitate transcription, which is the process whereby genetic information encoded in DNA is transferred to RNA. The information is carried in only one of the two strands of DNA, which is called the coding strand.
