Can rna form helices
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). WebRNA cannot form helices. Which is NOT a difference between RNA and DNA? A. RNA contains uracil; DNA usually does not. B. The sugar ring of RNA is more oxidized than that in DNA. C. RNA is usually single-stranded; DNA is double-stranded. D. RNA cannot form helices. Question Which is NOT a difference between RNA and DNA? Expert Solution

WebThe nucleotides in DNA and RNA have three components: a sugar group, a nitrogenous base, and a phosphate group. Adjacent nucleotides in a nucleic acid are joined by a phosphodiester bond. This bond links the phosphate group of one nucleotide to which one of the following components of a neighbouring nucleotide? a) Sugar b) Base c) Phosphate … WebTriple helix DNA and RNA are stabilized by many of the same forces that stabilize double-stranded DNA helices. With nucleotide bases oriented to the inside of the helix, closer to its axis, bases engage in hydrogen bonding with other bases.
WebApr 4, 2014 · The RNA adopts a compact structure with helices P1 and P2 stacked coaxially and helix P3 at an acute angle relative to P1 (Fig. 1D), consistent with other RNA three-way junctions of this class . Helices P1 and P3 form a ring-like structure defined by nucleotides 33–49, which comprise a continuous loop that resides entirely on one side of …
