Gene Expression I (INP)

What is gene regulation?

• The process of DNA replication

• The conversion of the information encoded in a gene into a functional product

• The synthesis of lipids

• The folding of proteins

Which enzyme is primarily responsible for transcription in eukaryotic cells?

• DNA polymerase

• RNA polymerase

• Helicase

• Ligase

What is the name of the process by which mRNA is translated into protein?

• Transcription

• Translation

• Replication

• Splicing

Which of the following is NOT involved in the regulation of gene expression?

• Ribosomes

• Enhancers

• Promoters

• Transcription factors

What type of RNA does RNA Polymerase I primarily synthesize?

• tRNA

• mRNA

• rRNA

• snRNA

What is the role of the TATA box in eukaryotic gene expression?

• It signals the end of translation

• It acts as a promoter region for transcription initiation

• It binds ribosomes for protein synthesis

• It helps in DNA replication

Which process removes introns from pre-mRNA in eukaryotic cells?

• Translation

• Splicing

• Polyadenylation

• Capping

Which of the following best describes the role of a promoter in gene regulation?

• The promoter codes for a specific protein involved in gene expression.

• The promoter is a DNA sequence that acts as a binding site for RNA polymerase to initiate transcription.

• The promoter inhibits transcription by preventing RNA polymerase from binding.

• The promoter is an RNA sequence that regulates the translation of proteins.
