“…If the size of the half window is a multiple of 10 (one helical turn) the amplitude of curvature of the (CT 4 A 4 G) n fragment is near to 0. This is consistent with the fact that oppositely oriented bends, in this motif, are mutually compensated in one turn (Stefl et al, 2004). The present example shows how a change in the size of the sliding window can be adopted for specific research tasks.…”

“…Although, when isolated, there are only 32 unique trinucleotides, once placed in the context of this motif, each of the 64 possible trinucleotides becomes unique. For example, the TTT sequence in this motif defines the overall sequence d(C-CAAATTTGG); the AAATTT central core of this sequence is associated with highly curved B-DNA (11,12). In contrast, the complementary AAA sequence would be found in d(CCTTTA-AAGG), where the TTTAAA core is known to not show significant curvature of the DNA helix.…”

“…A-Tract bending of DNA is known to highly depend on the sequence [49]. An A4T4-containing DNA duplex is bent towards the minor groove at the AT/AT step in the middle, whereas the T4A4-containing molecule shows the opposite behavior and bends towards major groove at the middle TA/TA step [50]. An RNA crystal structure of a construct consisting of only A and U nucleotides has been reported to feature two notable kinks in the helical axis [51] [52].…”
