MeSH definition : A cross-shaped DNA structure that can be observed under the electron microscope. It
is formed by the incomplete exchange of strands between two double-stranded helices
or by complementary INVERTED REPEAT SEQUENCES that refold into hairpin loops on opposite
strands across from each other.;
