Thus, the presence of the extra A.T base pairs between the binding sites appears to prevent the formation of Hoogsteen base pairs immediately adjacent to the binding site. All four central A.T base pairs are destabilized relative to those in the free DNA. Because there is no evidence for ...
Given that the ACGT core sequence is dispersed across promoters of various plant species; and that they occur in multiple copies with a variable number of base pairs separating them, we have attempted to analyze patterns in occurrence of ACGT core element repeats in plant genomes. We performed a...
pairs separating them, we have attempted to analyze pat- terns in occurrence of ACGT core element repeats in plant genomes. We performed an in-silico search for ACGT elements separated by spacers of varying lengths in all identified promoters for two monocots – Sorghum and Rice, and two dicot...
