Document Summary
Something that affects transcription (in both a positive and negative way) Affects transcription - turns gene on or off or affects expression. Protein that controls the rate of transcription of genetic information from dna to mrna by binding to a specific dna sequence transcription transcribed into dna. Protein that binds to dna and regulates gene expression by promoting or suppressing. Molecule that control the activity of a gene by determining whether the gene"s dna is. Protein involved in the process of converting or transcribing dna into rna. Does not always need to bind dna. 90% of the time it binds dna. There are scenarios where transcription factor can bind other transcription factors and prevents those from binding. Sequesters the positive transcription factors away from the gene. Over 2,000 transcription factors identified to date. Tfii proteins bind to all gene. Rna polymerase ii is not considered a transcription factor (it just binds dna)
