When a nucleotide binds, the fingers domain rotates 60° toward the palm, with the tops of the fingers moving by 30 Å. The thumb domain also rotates toward the palm by 8°. 

These changes are cyclical:

They are reversed when the nucleotide is incorporated into the DNA chain, which then translocates through the enzyme to recreate an empty site.

The K+ that enters hair cells via the mechanically-sensitive cation channels is recycled. In the cochlea, K+ eventually reaches the stria vascularis and is secreted back into the endolymph, completing the cycle

An actual overlapping gene occurs when the same sequence of DNA encodes two nonhomologous proteins because it uses more than one reading frame.
