Which of the Following Is True of Transcription Factors Quizlet

In bacteria transcription can be initiated only when sigma binds to the -35 and -10 boxes of the promoter in the DNA. This arrangement of genes is common in bacteria.

Mtc 17 Transcription Factor Flashcards Quizlet

An operon is a region of DNA that codes for a series of functionally related genes under the control of the same promoter.

. Which of the following is true of transcription. CIn eukaryotes transcription takes place in the cytoplasm and requires many enzymes. Because of the asymmetry and distinct sequences of the -35 and -10 boxes of the promoter the sigma protein can bind the promoter in only one orientation.

Orphan nuclear hormone receptors no. C They initiate the epinephrine response in animal cells. In bacteria transcription of a gene is initiated when the RNA polymerase by itself recognizes and binds to the promoter of the gene.

To a signal D They control gene expre E They transcribe ATP into B They initiate the epinephrine response in animal cels. A They regulate the synthesis of DNA in response to a signal. ARNA editing removes the exons from pre-mRNA leaving only the introns in the final molecule.

The initiation of gene transcription in eukaryotes requires the binding of proteins called transcription factors to the TATA box in the promoter region of a gene. The orientation of the promoter determines. Which of the following best defines an operon.

B Sigma factors are parts of RNA polymerase that recognize promoter regions. 6j they always lead to the. D They control gene expression.

Highly conserved DNA binding domain binding to genomic DNA sequences to regulate transcription. Definition of operon. Located in cytosol or nucleus 3.

A It occurs in the nucleoid region. Phosphoryation cascades involving a series of protein kinases are useful for cellular signal transduction because A they are species specific. Which of the following is true of transcription factors.

E They regulate the synthesis of. What is an operon in simple terms. BRNA polymerase recognizes and binds to specific regions of the DNA called introns.

C The same RNA polymerase transcribes primer RNA mRNA tRNA and rRNA. Which of the following statements concerning transcription in bacteria is FALSE. Small lipophilic molecules and xenobiotics.

- Specific Binding Orientation. D Termination is either self-induced or due to the presence of Rho protein. B They transcribe ATP into cAMP.

A group of closely linked. 29 which of the following is true of transcription factors.
