In Exercises 4552, sketch the graph of the piecewise-defined function. 1Try doing it without a calculator.) In each case, give any points of discontinuity.1x2 = e x if x 0 x 2 if x 7 0
Lecture 4-7-16 Review of Chapter 15 Eukaryotic system and how proteins are sorted and sent to specific destinations. They are identified by a stretch of amino acids in the genome (DNA) and that is what tells where they will go in the cell. Some will be identified by sequence at N-terminus and some will be at C-terminus. Specific for ER proteins To be imported- at the N-terminus Retention- KDEL No retention signal- protein will be secreted from ER ** Review experiment from slide. Features of sequence tag Signal sequence is necessary (needed to reach destination) Signal sequence is sufficient ( Modes of transport Nuclear pore – protein can be folded Translocation (across membrane)- protein has to be linear Vesicular transport
