Guanine pentaphosphate inhibits these sequences as part of the stringent response in bacteria.
Guanine pentaphosphate inhibits these sequences as part of the stringent response in bacteria. The activity of these sequences can be assessed by repeated mutagenesis in a technique called "bashing." Sequences of this type derived from simian virus 40 and cytomegalovirus are commonly used in expression vectors. Bidirectional examples of these sequences, which are especially common in mammals, are abundant in CpG islands. The sigma-70 factor recognizes part of this sequence called the Pribnow box. In archaea and eukaryotes, the negative-10 position of these cis-regulatory elements contains a consensus sequence beginning with TATA. Repressors block the attachment of RNA polymerase to these regions. For 10 points, name these regions of DNA that initiate transcription.
