Although RNA is a single-stranded molecule ... and anticodon takes place over three nucleotides, strict complementary base-pairing is only necessary between the first two nucleotides.

The complementary nature of base pairing allows for the accurate replication of DNA during cell division and the transcription of DNA into RNA for protein synthesis.

micro RNAs (miRNAs) are a type of non-coding RNA (ncRNA), ~21 24 nucleotides ... Typically miRNAs interact with specific mRNAs through complementary base-pairing to influence the translation ...

In the double helix structure of DNA, thymine forms a base pair with adenine through two hydrogen bonds. This specific pairing is known as complementary base pairing and is essential for the stability ...

These RNA ranks are simple structures stabilized by the formation of complementary base pairs ... is stabilized by A-U and G-C pairing and base-to-base stacking forces. The UB professor adds ...
