Document Summary
Lecture 14/15 o o o o o o. Watch for polyadenylaion signal (ends up in mrna) Proteins bind onto mrna and cut it right ater the polyadenylaion signal. Splice signals at the boundary between introns and exons. Recognized by snrps (by complementary base pairing between signal and the mrna) One gene can make muliple proteins (through alternaive splicing) Eukaryotes don"t rely on sd boxes (they are atracted to the 5" cap) Muliple ribosomes can simultaneously translate a single eukaryoic mrna (go. Synthesis of all proteins begins on cytosolic ribosomes. If it"s a chloroplast protein for example is gets a tag (targeing sequence is the irst to come out of the ribosome) If it goes to the cell membrane or is exported go to the rough er. Translaion begins in the cytosol but the ribosomes move to the. Er and the proteins are made into the er. Diferent types of mutaions in protein coding genes.
