139. (b) role of the synthesis and degradation of mRNA in cell functioning (Because all the three paras tell about the effect of the "synthesis and degradation of mRNA" on the cell"
140. (a) The rate of degradation of specific mRNA’s has little effect on protein concentrations (Because the protein concentrations is affected by the synthesis of different mRNA’s)
141. (c) The third paragraph describes a specific case of a phenomenon that is described generally in the second paragraph (Because the second para tells about the effect of the "variable rates at which cells degrade" and the third paragraph gives the example of "the development of red blood cells")
142. (a) The effectiveness of simultaneous variation of the rates of synthesis and degradation of mRNA (Because "most cells can regulate protein production most efficiently by varying both mRNA synthesis and degradation")
143. (a) only the degradation rate for the mRNA of the protein involved (Because most mRNA’s correlate best with the degradation rate rather than the synthesis rate)
144. (b) Degradation of mRNA is now considered to be as important as mRNA synthesis has been, and still is, believed to be (Because the para 2 tells about the importance of the degradation of the mRNA)
145. (b) Cancer can result from an excess of certain proteins and diabetes can result from an insulin deficiency (Becasue the para 1 gives these two examples)
146. (d) The mRNA’s for both proteins are being degraded at a low rate in that type of cell (Because the second para tells that "a cell degrades both a rapidly and a slowly synthesized mRNA slowly, both mRNA’s will accumulate to high levels"
