Sequence-Dependent Variability of B-DNAns, particularly bending, of the double helix. The A-tract curvature, which modulates these processes, has thus been a subject of long-standing interest. Here we describe the ongoing evolution of models developed to account for the sequence-dependent bending and curvature of DNA, namely the AA-wedge

Curved DNA and Prokaryotic Promotersci, and are found in a wide variety of cellular and viral genomes from bacteria to man. In bacterial promoters, bent DNA structures are often located from immediately upstream of the −35 hexamer to around position −100 relative to the transcription start site (+1). They have a range of functions: fa

Curved DNA and Transcription in Eukaryotesall class I gene promoters. Although not all class II gene promoters contain curved DNA structures, both TATA-box-containing and TATA-box-less promoters often contain such structures. Furthermore, several studies have suggested that the TATA box itself adopts a curved DNA conformation. Curved DNA st

Roles for Z-DNA and Double-Stranded RNA in Transcriptionmples where genetic information is encoded by shape rather than by sequence. The use of these two conformational motifs to produce sequence-specific changes in RNA transcripts is discussed using dsRNA editing by ADAR1 as a model. This concept is extended to other RNA-directed modifications of DNA an

Do DNA Triple Helices or Quadruplexes Have a Role in Transcription?exes and four-stranded DNA quadruplexes. Several lines of evidence suggest that multiplex structures can form in vivo, either from the addition of oligonucleotides or through the transient formation of single-stranded regions. The consequences of multiplex structures on many DNA-dependent biological
