Multiple Choice

Scenario
You conducted a series of experiments to test whether the expression of hexokinase, an important enzyme involved in glycolysis, varies under different conditions. In the first experiment, you measured the production of hexokinase mRNA in cells at three different temperatures: 37°C, 25°C, and 10°C. Your results showed that the mRNA levels for hexokinase were 5× and 20× lower at 25°C and 10°C than at 37°C, respectively. Based on these results, you are going to conduct further experiments to attempt to answer your research question.
-What can you conclude from these results?

• A)Unpacking of the hexokinase gene occurs only at 37°C.
• B)Transcription of the hexokinase gene occurs less frequently at lower temperatures.
• C)The levels of hexokinase protein are not affected by temperature.
• D)Translation of the hexokinase gene occurs more frequently at higher temperatures.
