WebA'-form RNA helices are required for cytoplasmic mRNA transport in Drosophila. Microtubule-based mRNA transport is widely used to restrict protein expression to … 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
WebAnswer: RNA can be single-stranded or form a double-stranded RNA double helix. RNA also forms lots of interesting structures with loops and such that make compact shapes like a ‘clover leaf’ or other structures. RNAs form only short double helices, unlike DNA, but RNA double helices are short. N... WebRNA chains fold back on themselves to form hairpin loops or stem-loops, so that these sequences can form helices. Many of the helical stems in RNA hairpins are interrupted by internal loops, which is to say regions where sequences are juxtaposed that can-not form GCs, AUs, or wobble GUs, which most regard as “honorary” Watson-Crick base pairs.

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 …
WebThe free energy of an RNA fold is a combination of favorable base pairing and stacking interactions competing with entropic costs of forming loops. Here we show how loop entropy, surprisingly, can promote tertiary order. A general formula for the free energy of forming multibranch and other RNA loops is derived with a polymer-physics based theory. We …
