Answer is "regulatory proteins that bind to specific DNA sequences."
Transcription factors controls the rate of transcription of genetic information from DNA to messenger RNA, by binding to a specific DNA sequence.

Nucleosome positioning along the DNA can influence where transcriptional regulatory proteins are able to bind DNA. If a nucleosome is bound to an enhancer sequence, it may outcompete a regulatory protein from binding the same sequence. Conversely, if an enhancer sequence is in the linker DNA where the nucleosome is absent, the regulatory protein does not have to compete with the nucleosome. The position of the nucleosome can alter the accessibility of a sequence of DNA to DNA binding proteins....

3. This is a schematic of a very simple pattern of gene expression. Yes means the protein is present and can bind the promoter. No means the protein is absent. Transcription factors are proteins that help regulate transcription by binding DNA Activators are transcription factors that help transcription. For example, they bend the promoter and make it accessible to RNA polymerase. Repressors are transcription factors that inhibit transcription. For example, they might bind the promoter and stop the RNA polymerase...

Classify each statement according to whether it applies to general transcription factors only, specific transcription factors only, both, or neither These transcription factors are found in both prokaryotes and eukaryotes. These transcription factors are proteins. These transcription factors form part of the transcription complex. One of these transcription factors binds directly to the TATA box in the core promoter. These transcription factors bind to the operator. These transcription factors bind to enhancer sequences that may be distant from the promoter....

Which of the following correctly describes eukaryotic transcriptional control? a. A transcription factor is a DNA molecule that helps RNA polymerase to bind to the enhancer of a specific gene. b. An enhancer is a protein that encourages gene expression by binding to the DNA. c. The promoter is the region of RNA where DNA polymerase will bind to begin transcription. d. The interaction of multiple transcription factors may be required in order to transcribe a...
An experiment was conducted to determine the effects of a novel promoter on the transcription of a gene.
An experiment was conducted to determine the effects of a novel promoter on the transcription of a gene. The cloned promoter and coding regions were ligated to luciferase, a reporter gene. Several regions of DNA in the promoter region were deleted. Each construct was transformed into cells, and the luciferase activity was measured. The data from the experiment is listed in the table.Which conclusions can be drawn from the data?-Transcription increases when region A is deleted because the promoter region...

You are studying the regulatory DNA of a mouse gene expressed in developing heart, liver, and lung tissue. Your preliminary work has shown that heart and lung expression of this gene is controlled by a short fragment of DNA just upstream of the promoter. Based on this result, you decide to investigate this region further to understand its function. Part A You decide to compare this sequence to the regulatory DNA of the same gene found in rats and humans....
