Transcription factors bind to DNA enhancer regions to regulate gene expression. These proteins recognize specific DNA sequences and play a key role in activating or repressing the transcription of nearby genes. Enhancers can be located far away from the genes they regulate, and their binding by transcription factors helps to control when and to what extent a gene is expressed.

3 DNA does NOT contain the nitrogen base?
DNA does not contain uracil. RNA does!! DNA contains guanine binds with Thymine in DNA RNA contains guanine that binds with uracil DNA does not contain uracil. RNA does!! DNA contains guanine binds with Thymine in DNA RNA contains guanine that binds with uracil
How is a promoter region different from an operator region?
A promoter region is the site where RNA polymerase binds to initiate transcription of a gene, while an operator region is a site where a repressor protein binds to regulate gene expression by blocking the binding of RNA polymerase. Promoter regions are involved in the initiation of transcription, while operator regions are involved in the control of transcription.
In DNA what does adenine always pair up with?
In DNA, adenine always pairs up with thymine. This pairing is based on hydrogen bonding, which allows adenine and thymine to form a complementary base pair.
In DNA adenine binds with?
In DNA, adenine binds with thymine through two hydrogen bonds in the complementary base pairing scheme.
What process begins at the promoter of DNA?
Transcription begins at the promoter of DNA. The promoter region is where RNA polymerase binds to initiate the process of copying a gene into messenger RNA (mRNA).
In eukaryotes the interaction of enhancer and promoter elements is brought closer by?
In eukaryotes, the interaction of enhancer and promoter elements is brought closer by the bending of DNA. Proteins called transcription factors bind to enhancer elements and recruit complexes that help bend and loop the DNA, bringing the enhancer and promoter regions into close proximity for efficient gene expression.
What region of the DNA does the giemsa stain dye?
Giemsa stain binds the regions with high content of adenine-thymine complex.
During protein synthesis in eukaryotic cells does the activator-enhancer complex the molocule of DNA so other transcription factors have better acces tothe bonding sites on the operator?
Yes. If I understand your question correctly (I cleaned up the wording slightly). Activators are proteins that bind to enhancer regions of DNA. This facilitates the binding of transcription factors and the RNA Polymerase to read the DNA of the gene.
Where is dna located in a eukaryote cell?
in the nucleus
What is the mRNA for DNA molecule t-a-c- c- g -g?
If a DNA strand read CCTAGCT, its mRNA would read GGAUCGA.
What molecules are found in a DNA nucleotide?
Guanine which binds with Cytosine, and Adenine which binds with Thymine.
What Nucleotides pairs are found in a DNA molecule?
Guanine which binds with Cytosine, and Adenine which binds with Thymine.
What happen to lac repressor in E. coli when lactose is present?
E. coli binds with lactose which changes its conformation so that it no longer binds to DNA. This allows the lactose operon to be transcribed.
In DNA replication adenine bindes with what?
In DNA replication A (adenosine) binds to T (thymidine).
What binds to the DNA strand and separates it?
helicase enzyme
What is the protein that binds DNA into tight coils?
histone
How is complementary base pairing different when pairing DNA to DNA than DNA to mRNA?
Complementary base pairing in DNA-DNA pairing involves adenine (A) bonding with thymine (T) and guanine (G) bonding with cytosine (C), following the standard A-T and G-C base pairs. In DNA-mRNA pairing, uracil (U) replaces thymine (T) in RNA, so adenine (A) in DNA pairs with uracil (U) in mRNA, while guanine (G) still pairs with cytosine (C) in RNA.
