WebAll cellular RNA and DNA is synthesized in the nucleus, but the attachment of amino acids to tRNAs for protein synthesis, catalysed by aminoacyl-tRNA synthetases, occurs in the cytosol. In cells in which protein synthesis is occurring at a rapid rate, the concentration of the transferase enzymes in the cytosol is very high and they can form a ... WebAfter translation, proteins within the ER make sure that the protein is folded correctly. If after a first attempt the folding is unsuccessful, a second folding is attempted. If this fails too the protein is exported to the cytosol and labelled for destruction. Aside from the folding, there is also a sugar chain added to the protein. onpagefinished执行多次
