Transcription Quiz

What is RNA transcription?

• The process of breaking down RNA into its component nucleotides.

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

• The process of making a protein from an RNA sequence.

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

Where does RNA transcription occur in a eukaryotic cell?

• nucleus

• cytoplasm

• cell membrane

• mitochondria

What is the role of RNA polymerase in transcription?

• It synthesizes RNA from a DNA template.

• It regulates gene expression

• It converts RNA into DNA

• It repairs damaged DNA strands

What is the function of the promoter in transcription?

• Regulates the translation of mRNA

• Stops the transcription process

• Repairs damaged DNA during transcription

• Initiates the transcription of a particular gene

What are the three types of RNA produced during transcription?

• mRNA, tRNA, and rRNA

• DNA, RNA, and protein

• Ribosome, nucleus, and cytoplasm

• mRNA, tRNA, and DNA

What is the significance of transcription in protein synthesis?

• Transcription is only important for DNA replication.

• Transcription has no significance in protein synthesis.

• Transcription creates carbohydrates for energy production.

• Transcription creates RNA that is used as a template for protein synthesis.

How does RNA transcription differ from DNA replication?

• RNA transcription produces proteins from a DNA template

• RNA transcription produces RNA from a DNA template, while DNA replication produces an exact copy of a DNA molecule.

• DNA replication produces RNA from a DNA template

• RNA transcription produces DNA from an RNA template

Which enzyme is responsible for unwinding the DNA double helix during transcription?

• RNA polymerase

• Helicase

• Ligase

• Topoisomerase

What is an anticodon?

• A sequence of three nucleotides forming a unit of genetic code in a DNA molecule.

• A sequence of three nucleotides forming a unit of genetic code in a tRNA molecule, complementary to a codon in mRNA.

• A type of enzyme that helps in the replication of DNA.

• A structural component of the ribosome's large subunit.

Which molecule is responsible for carrying the anticodon?

• mRNA

• rRNA

• tRNA

• DNA
