If the strands come together with base pairing, the fluorescence resonance energy transfer between the fluorophores is facilitated.

These base pairings are not seen in other species (see below).

It can replicate because the specificity of base pairing ensures that the daughter molecules are identical to the original one.

The miR-122 hairpin precursor consensus shown here is predicted based on base pairing and cross-species conservation.

Transmission of genetic information in genes is achieved via complementary base pairing.

In terms of base pairing, this has no effect.

Much of this base pairing can be represented in a context-free grammar (the major exception being pseudoknots).

This means its 5' end is created first in base pairing.

Revertants that restored base pairing were also identified.

They are single stranded covalent circles and have intramolecular base pairing.
