What is gene expression determined by?

• Coding regions

• Non-coding regulatory regions

• Ribosomes

• Enzymes

What is the process of copying DNA information into mRNA called?

• Translation

• Transcription

• Mutation

• Gene expression

What is the process of using mRNA to make proteins called?

• Transcription

• Translation

• Gene expression

• Mutation

What would be the mRNA sequence transcribed from the DNA sequence ATGGCCTAA?

• UACCGGAUU

• TACCGGATT

• AUGGCCUAA

• ATGGCCTAA

Which statement best explains why changes in non-coding DNA regions can affect protein production even when the gene sequence is normal?

• Non-coding DNA contains the instructions for making proteins

• Non-coding DNA controls when and how much the gene is expressed

•    Non-coding DNA directly produces proteins

•    Non-coding DNA repairs damaged genes

What is the role of non-coding DNA regions?

• They control the gene

• They produce enzymes

• They digest proteins

• They are identical in all humans

Gene expression occurs when:

• DNA is copied during cell division

• A gene is activated by non-coding DNA to make a protein

• Mutations occur in the DNA sequence

• Non-coding DNA is removed
