What is the process called when DNA is converted to RNA?

• Transcription

• Translation

• Replication

• Mutation

Where does the translation process occur?

• Cytoplasm

• Nucleus

• Mitochondria

• Golgi apparatus

In eukaryotic cells, what process occurs between transcription and translation?

• RNA splicing

• DNA replication

• Protein folding

• Glycolysis

Is DNA double-stranded or single-stranded?

• Double-stranded

• Single-stranded

What base is found in DNA instead of uracil?

• Adenine

• Thymine

• Cytosine

• Guanine

What is the role of pre-mRNA in the cell?

• A) Precursor to mRNA, newly transcribed and not edited

• B) Carries a specific amino acid to ribosome

• C) Makes up 60% of the ribosome

What is the function of mRNA?

• Edited version; carries the code from DNA that specifies amino acids

• Part of a spliceosome; structural and catalytic roles

• Signal recognition particle that binds to signal peptides

What does tRNA do in the cell?

• Interference RNA; a regulatory molecule

• Carries a specific amino acid to ribosome based on its anticodon to mRNA codon

• RNA that functions as an enzyme

What is the role of rRNA?

• Makes up 60% of the ribosome; site of protein synthesis

• Micro/small interfering RNA; binds to mRNA or DNA to block it

• Precursor to mRNA, newly transcribed and not edited
