What is the difference between an enhancer and a transcription factor in gene regulation?
An enhancer is a DNA sequence that can increase the activity of a nearby gene, while a transcription factor is a protein that binds to DNA and helps regulate the transcription of genes. Enhancers can be bound by transcription factors to enhance gene expression.
Which enzyme binds to DNA during transcription?
RNA polymerase is the enzyme that binds to DNA during transcription.
How does RNA polymerase determine its binding location on the DNA strand?
RNA polymerase determines its binding location on the DNA strand by recognizing specific sequences of nucleotides called promoter regions. These promoter regions contain signals that indicate where the RNA polymerase should start transcribing the DNA into RNA. The RNA polymerase binds to these promoter regions with the help of other proteins, allowing it to initiate the transcription process at the correct location on the DNA strand.
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
In DNA what does adenine always pair up with?
In DNA replication, adenine binds with thymine. In RNA, adenine binds with uracil.
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 is the difference between an enhancer and a transcription factor in gene regulation?
An enhancer is a DNA sequence that can increase the activity of a nearby gene, while a transcription factor is a protein that binds to DNA and helps regulate the transcription of genes. Enhancers can be bound by transcription factors to enhance gene expression.
What region of the DNA does the giemsa stain dye?
Giemsa stain binds the regions with high content of adenine-thymine complex.
Where is dna located in a eukaryote cell?
in the nucleus
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.
Which enzyme binds to DNA during transcription?
RNA polymerase is the enzyme that binds to DNA during transcription.
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.
How does RNA polymerase determine its binding location on the DNA strand?
RNA polymerase determines its binding location on the DNA strand by recognizing specific sequences of nucleotides called promoter regions. These promoter regions contain signals that indicate where the RNA polymerase should start transcribing the DNA into RNA. The RNA polymerase binds to these promoter regions with the help of other proteins, allowing it to initiate the transcription process at the correct location on the DNA strand.
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).
