Predict the location(s) (intracellular or extracelular) and a brief description of WHY based on your knowledge of the transport processes in the following constructs. Assume a start codon is present and include any proteolytic processing that would be likely. 1. A PTS1 C-term peroxisomal targeting seq added to C term of a normally secreted protein with usual N -terminal signal sequence 2. Adding of N-terminal mitochondrial targeting sequence to protein with internal nuclear localization seq. 3. Adding N-terminal signal sequence of secreted protein to N-terminus a mitochondria matrix protein precursor with mitochondrial targeting sequence still present
