Can dna form hairpins
WebSep 9, 2024 · How do RNA hairpins differ from DNA hairpins? The stem of the RNA hairpin exhibiting a A-form helical structure is shorter and therefore more compact than the stem of the DNA hairpin, which is a B-form double helix. In the RNA helix, the constraint caused by the opening fork may thus more easily extend over several base pairs than in … WebApr 24, 2024 · 3.
