... Transcription of a gene by RNA polymerase can be regulated by at least three types of proteins: Specificity factors alter the specificity of RNA polymerase for a given promoter or set of promoters, making it more or less likely to bind to them. Repressors bind to non-coding sequences on the DNA stra ...
