Question

what could happen if a gene that is normally off becomes activated?
○ the cell will stop producing all proteins
○ the cell may make the wrong proteins and function incorrectly
○ nothing will change because genes do not affect cells
○ the cell will turn into a completely different organism

Explanation:

• Analyze Option 1: A gene activation won't stop all protein production, as other genes still function. Eliminate this.
• Analyze Option 2: Genes code for proteins. A normally off gene activating may lead to producing a protein it's coded for, which might be inappropriate for the cell's normal state, causing wrong proteins and incorrect function. This is plausible.
• Analyze Option 3: Genes directly affect cells by coding for proteins, so "nothing will change" is wrong. Eliminate this.
• Analyze Option 4: A single gene activation can't turn a cell into a completely different organism; that's a gross overstatement. Eliminate this.

Answer:

B. The cell may make the wrong proteins and function incorrectly
