AP Bio Unit 6 Review: Transcription Quiz

What is transcription?

• The process of duplicating a gene's DNA sequence

• The process of making an RNA copy of a gene's DNA sequence.

• The process of creating a protein from RNA

• The process of converting RNA into DNA

Where does transcription occur in a eukaryotic cell?

• cytoplasm

• mitochondria

• endoplasmic reticulum

• nucleus

What is the role of RNA polymerase in transcription?

• It translates mRNA into protein

• It repairs damaged DNA strands

• It breaks down RNA into nucleotides

• It synthesizes an RNA molecule from a DNA template.

What are the three main steps of transcription?

• Start, middle, end

• Beginning, middle, conclusion

• Initiation, elongation, and termination

• Commencement, extension, conclusion

What is the function of the promoter in transcription?

• Stops the transcription process

• Regulates translation of mRNA

• Initiates the transcription of a particular gene

• Repairs damaged DNA

What is the difference between the coding strand and the template strand in transcription?

• The coding strand is not used as a template for RNA synthesis, while the template strand is used to synthesize RNA.

• The coding strand is used to synthesize RNA, while the template strand is not used

• The coding strand and the template strand are the same thing

• The coding strand is used as a template for RNA synthesis, while the template strand is not used

What is the purpose of transcription factors in eukaryotic transcription?

• To prevent RNA polymerase from binding to the promoter region

• To help RNA polymerase bind to the promoter region and initiate transcription.

• To degrade the mRNA after transcription

• To inhibit RNA polymerase activity

What is the significance of the TATA box in transcription?

• It acts as a termination signal for the transcription process

• It helps to stabilize the DNA double helix

• It is responsible for splicing the introns from the pre-mRNA

• It helps to position the RNA polymerase for transcription to begin.

How is pre-mRNA modified after transcription in eukaryotic cells?

• Polyadenylation, replication, and translation

• Capping, translation, and polyadenylation

• Capping, splicing, and polyadenylation

• Splicing, transcription, and methylation

What is the role of RNA splicing in eukaryotic gene expression?

• RNA splicing has no role in gene expression

• RNA splicing removes introns and joins exons together.

• RNA splicing creates new genes

• RNA splicing increases the number of introns
