The image below shows (A) RNA blot analysis (hsp1) and (B) protein abundance for Heat shock protein (HSP) and Actin. At \( t=0 \) a culture of Chlamydomonas cells was shifted from \( 24^{\circ} \mathrm{C} \) to \( 40^{\circ} \mathrm{C} \). Which of the following explanations is most consistent with the data shown? A. It is likely that the rate of translation is similar for both HSP and Actin at \( 0 \mathrm{hr} \). B. The decrease in transcript abundance in hsp1 from 4 to \( 24 \mathrm{~h} \) can be explained by an increase in mRNA decay. mRNA decay. C. The increase in HSP protein abundance over time is probably not due to an increase in hsp1 transcription. D. Because Actin shows constant levels over time, the transcription of Actin has probably stopped.
