Where are the promoter and operator sequences located?
Promoter and Operator are important DNA sequences that are involved in the transcription process and in transcription regulation. Promoter sequences are found in both prokaryotes and eukaryote. Promoter is the site for binding of RNA polymerase.
What is the relationship between promoter sequence and its strength?
Relationship between promoter sequence and its strength in gene expression. Promoter strength, or activity, is important in genetic engineering and synthetic biology. A constitutive promoter with a certain strength for one given RNA can often be reused for other RNAs.
What is the role of a gene promoter?
Gene promoters are the ignition system of genes and harbor regions of DNA (cis-acting elements) that provide binding sites for mostly nuclear proteins (transcription factors) that enhance or suppress transcriptional activation. A gene promoter is the genomic DNA sequence immediately upstream of the transcription start site.
