Witryna1 kwi 2009 · The Promoter of a Gene. The promoter , a regulatory region of DNA located upstream of a gene, plays an important role in transcriptional regulation. The core promoter, a loosely defined region (approximately between nucleotides −40 and +50 from the transcriptional start site [TSS]), directs low-level transcription. Witryna15 wrz 2024 · Promoters are made of nucleic acids. A promoter is a sequence of DNA bases which is upstream of the transcription start site of a gene. Do all genes have a promoter? Every gene has a promoter, which is the binding site for the basal transcriptional apparatus – RNA polymerase and its co-factors.

WitrynaThe promoter is regulated by binding of the repressor at the operator, lacO, and of Crp protein at the Crp site. Note that in reality the operator partly overlaps both the promoter and the structural gene. The single lac mRNA is translated to produce the LacZ, LacY, and LacA proteins. WitrynaCHA1 of Saccharomyces cerevisiae is the gene for the catabolic L-serine (L-threonine) dehydratase, which is responsible for biodegradation of serine and threonine.
