All genes regulated by PKA contain a cis-acting DNA sequence that binds to the phosphorylated form of a transcription factor called (choose one answer)
CREB
TCF
beta-catenin
C-Jun
A cellular transcription factor, CREB (cAMP response element-binding protein) binds to particular DNA sequences called CRE (cAMP response elements), thus, increases or decreases the transcription of the genes. Thus, all genes regulated by PKA consisting of a cis-acting DNA sequence that binds with the transcription factor is called CREB.
Hence, "CREB" is the correct answer.

What is an operon? Choose one: A. a short sequence of DNA to which a transcription regulator binds B. a set of genes that is constitutively active C. a sequence of DNA that produces a variety of mRNAs RD. a set of genes controlled by the binding of two or more transcription regulators E. a set of genes transcribed as a single mRNA from a single promoter
There are some significant differences in how transcription is regulated in prokaryotes like E. coli versus eukaryotes. Which of the following statements concerning gene regulation is TRUE only in eukaryotes? (CHOOSE ALL THAT APPLY AND NO INCORRECT ANSWERS) The promoter of a gene can act in a position and distance-independent manner. The genes involved in one process are usually situated next to each other in the genome and are transcribed in one mRNA. The default state of gene transcription is...

A) anaphase promoting complex B) entry into S-phase of the cell cycle C) removal of the nuclear lamina D) removal of methyl groups from DNA E) histone de-acetylation 107. What does DNA Ligase do? A) removes mismatched nucleotides B) adds complimentary bases to single stranded DNA C) joins the ends of chromosomes together D) forms a phosphodiester covalent bond between adjacent nucleotides E) chews up single...
Which of the following might decrease the transcription of all genes in a bacterial cell? Select one: a. a decrease in the amount of sigma factor b. a decrease in the amount of RNA polymerase II c. a mutation that introduced extensive sequence changes into the DNA that precedes a single gene’s transcription start site d. a mutation that introduces a stop codon into the DNA that precedes the gene’s coding sequence
Yet, all the cells in your body contain the same
genes (and same alleles). The difference across cell types
is that genes get selectively expressed (turned on or off)
based on the proteins needed for cellular function given their
environment.

it
b.
Muscle cells do not have the gene for keratin and...

IFN-B level (% wildtype) The transcription and production of a protein called interferon-beta (IFN-B) is regulated by a transcription factor called IRF3, which binds to DNA as a dimer of two 30KD monomeric proteins. The DNA- binding site of IRF3 contains the following amino acids: Arg - Lys -lle. Thr. I create four mutants of IRF3 by changing one of the amino acids of the DNA-binding site to serine, and then measure the levels of IFN- I transcripts made...
