Document Summary
Plant and animal cells have similar organelles. Identical dna in different cells but different proteomes. Gene regulation: amount/type of protein, protein modification can influence cell"s. Proteomes in liver cells are different than neurons, skin etc proteome. Dna makes rna leave the nucleus to go into cytosol goes to ribosome to make protein. Give cells a pulse and watch the radioactive proteins a=with non radioactive. Wanna be able to follow a small population. Its another way to track the radioactive protein. machines that recognize the postcode though protein-protein interactions. If not remaining, er then it will be packaged at the er and be shipped off in a vesicle. The vesicle has to be able to bind to the specific membrane. Semiautonomous synthesis, cell is looking for code for instructions organelles make some of their own proteins but most are sorted post translationally. Some peroxisomal proteins are post translationally sorted. For mitochondria or chloroplasts the protein remains unfolded.
