Scientists can track the movement of proteins through the endomembrane system using an approach known as a pulse-chase experiment. This experiment involves • the "pulse" phase: Cells are exposed to a high concentration of a radioactively labeled amino acid for a short period to tag proteins that are being synthesized. • the "chase" phase: Any unincorporated radioactively labeled amino acids are washed away and large amounts of the same, but unlabeled, amino acid are added. Only those proteins synthesized during the brief pulse phase are radioactively tagged. These tagged proteins can be tracked through the chase period to determine their location in the cell. The data below were obtained from a pulse-chase experiment in which cells were examined at different times during the chase period. The numbers represent the radioactivity (measured in counts per minute) recorded at each of the indicated sites. The higher the number, the greater the radioactivity ER 162 Time 3 minutes 20 minutes 60 minutes 73 Golgi Cytoplasm Lysosomes Extracellular space 7 21 5 4 88 17 10 8 35 14 112 13 23 18 151 10 9 120 minutes 11 Based on these data, what of the following is the most likely function of the cells in this experiment?

MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER If an experiment is conducted, one and only one of three mutually exclusive events S, Sy, and Szcan occur, with these probabilities. P(S) = 0.1 P(S) = 0.5 P(Sz) = 0.4 The probabilities of a fourth event A occurring, given that event S, Szor Szoccurs, are the following. P(AIS) = 0.1 P(AIS) = 0.2 P(AS) = 0.4 If event A is observed, find P(S,A), P(S2/A), and P(Sz|A). (Round your answers to four decimal places.) P(SIA) = P(S21A) = P(S31A) = Need Help?
