Even though the anti conformation is favored with the purines the syn configuration can be formed and actually has a role in the formation of the Z-DNA, a ... |
The anti conformer has the smaller H-6 (pirimidine) or H-8 (purine) atom above the sugar ring, while the syn conformer has the larger O-2 (pirimidine) or N-3 ( ... |
The nucleosides in the DNA duplex adopt the anti conformation (there are very few exceptions to this rule, one of which is guanosine monophosphate, in which the ... |
Most base pairs exist in DNA or RNA in the anti conformation. However, in unpaired regions of RNA some bases can adopt the more compact syn conformation. |
The anti conformation of pyrimidines is stable as in the syn conformation, the sugar residues interferes with the pyrimidine's C2 substituent. |
Videolar 19 июл. 2021 г. · The two strands are held together by H‑bonding between the bases (in anti conformation) as shown in Figure 2.5.1. Major groove Major groove. |
In purine nucleosides, anti-conformation is marked by proximity of the hydrogen at C8 to C5', and in the case of syn-conformation N3 is above the plane of the ... |
