In a β pleated sheet, two or more segments of a polypeptide chain line up next to each other, forming a sheet-like structure held together by hydrogen bonds. WebConsistent with experiment, the relative energies favor B-form helices for DNA and A-form helices for the NP-modified system and for RNA. Salt effects, modeled at the linear or nonlinear PB level, favor the A-form helices by modest amounts; for d (ACCCGCGGGT) 2, salt is nearly able to switch the conformational preference to 'A'.

WebAug 1, 2024 · RNA (single or double stranded) actually can and does form a helix in the absence of certain complex 3D structures. The RNA helix is typically A-form, as opposed to B-form for typical DNA. The A-form helix is right-handed like the B-form but is more compact (2.6 Å rise versus 3.4 Å) and wider (26 Å diameter vs 20 Å).
