13 Mar 2018 Abstract. Promoter escape involves breaking of the favourable contacts between RNA polymerase (RNAP) and the promoter to allow transition

Recombination hotspots are DNA sequences that increase local recombination. The HOT1 sequence in yeast is one of the most well studied mitotic recombination hotspots. The HOT1 sequence includes an RNA polymerase I transcription promoter. In a yeast mutant strain defective in RNA polymerase I the HOT1 activity in promoting recombination is

The central part of the phage genome is not required for replication or packaging of λ DNA molecules in E. coli, so the central part can be cut out by using

Promoters are a vital component of expression vectors because they control the binding of RNA polymerase to DNA. RNA polymerase transcribes DNA to mRNA which is ultimately translated into a functional protein. 1998-06-15 Promoter Distortion and Opening in the RNA Polymerase II Cleft. Transcription initiation requires opening of promoter DNA in the RNA polymerase II (Pol II) pre-initiation complex (PIC), but it remains unclear how this is achieved. Here we report the cryo-electron microscopic (cryo-EM) structure of a yeast PIC that contains underwound, distorted 2013-01-07 In addition to the core promoter, other cis-acting DNA sequences that regulate RNA polymerase II transcription include the proximal promoter, enhancers, silencers, and boundary/insulator elements (e.g., see Blackwood and Kadonaga 1998; Bulger and Groudine 1999; West et al.

Mutations in the DNA polymerase beta (po1β) promoter may affect the transcription of this gene; however, the relationship between these mutations and the … A promoter is a region of DNA where transcription of a gene is initiated. Promoters are a vital component of expression vectors because they control the binding of RNA polymerase to DNA. RNA polymerase transcribes DNA to mRNA which is ultimately translated into a functional protein. 1998-06-15 Promoter Distortion and Opening in the RNA Polymerase II Cleft.

Here, we report cryo-EM structures of closed, intermediate and open Pol I cognate base pairs during promoter recognition.
