The hairpin structures created by the RAG proteins are opened by single endonucleolytic events (responsible enzyme unknown) adjacent to the hairpin end.

Synthesized as ~120 kDa precursors, they are inserted into membranes of the endoplasmic reticulum (ER) in a hairpin fashion. Both the N-terminal transcription factor domain and the C-terminal regulatory domain face the cytoplasm.

The terminator sequence is usually a palindromic sequence that forms a stem-loop hairpin structure that leads to the dissociation of the RNAP from the DNA template.One such common termination motif is the palindromic sequence 'GCCGCCAG'.

Also, a primer should not easily anneal with itself or others of its kind, building loops or hairpins in the process. This could hinder the annealing with the template DNA. However, small hairpins are usually unavoidable.

It is bent in a hairpin shape — the hypocotyl arch — as it grows up. The two cotyledons protect the epicotyl structures — the plumule — from mechanical damage.
