You Have Set Up a System of Differential Equations to Describe

question 10

Multiple Choice

You have set up a system of differential equations to describe the concentration of a protein as a function of time based on transcription, translation, and degradation rates. You simulate two conditions (1 and 2) that are identical except that the transcription rate for the protein is set tenfold higher in one of them (1) compared to the other (2) . Starting from a concentration of zero, the time required to reach 50% of the final steady-state concentration is …

• A) the same for conditions 1 and 2.
• B) tenfold longer for 1 compared to 2.
• C) tenfold longer for 2 compared to 1.
• D) less than tenfold longer for 1 compared to 2.
• E) less than tenfold longer for 2 compared to 1.
