Consider two proteins A and B with equal transcription and translation rates. The mean lifetime of A, however, is twice as long as that of B. Starting with no protein, the time it takes for a protein to reach 99% of its steady-state concentration is …
A) the same for proteins A and B. B) two times longer for A compared to B. C) two times longer for B compared to A. D) less than twofold longer for A compared to B. E) less than twofold longer for B compared to A.
