Transcription Regulation in Eukaryotic

What are transcription factors?

Name one example of a transcription factor.

• p63

• p21

• p73

• p53

What are promoter elements?

• Specific RNA sequences located upstream of a gene that initiate translation

• DNA sequences located downstream of a gene that initiate transcription

• Non-specific DNA sequences located upstream of a gene that inhibit transcription

• Specific DNA sequences located upstream of a gene that initiate transcription

What is the function of enhancers and silencers in transcription regulation?

• Enhancers decrease transcription and silencers increase transcription.

• Enhancers and silencers have no effect on transcription.

• Enhancers and silencers are only involved in translation, not transcription.

• Enhancers increase transcription and silencers decrease transcription.

How do enhancers and silencers affect gene expression?

• Enhancers can decrease gene expression, while silencers can increase gene expression.

• Enhancers can increase gene expression, while silencers can decrease gene expression.

• Enhancers and silencers have no effect on gene expression.

• Enhancers and silencers can both increase and decrease gene expression simultaneously.

What is chromatin remodeling?

• The process of altering the structure of chromatin.

• The process of repairing damaged chromatin.

• The process of duplicating chromatin.

• The process of changing the color of chromatin.

Name one mechanism of chromatin remodeling.

• RNA splicing

• ATP-dependent chromatin remodeling complexes

• DNA replication

• Histone modification

What are transcriptional activators?

• Proteins that inhibit gene transcription.

• Proteins that have no effect on gene transcription.

• Proteins that degrade gene transcription.

• Proteins that enhance gene transcription.

How do transcriptional activators regulate gene expression?

• Transcriptional activators have no effect on gene expression.

• Transcriptional activators degrade mRNA molecules.

• Transcriptional activators bind to enhancers or promoter regions to initiate transcription.

• Transcriptional activators inhibit gene expression.

Give an example of a transcriptional activator.

• p50

• p63

• p73

• p53
