Cells rely on proteins and many of the organelles in a eukaryotic cell are involved in the life of a protein. The instructions for the genetic code must be packaged and then read and a protein assembled from those instructions. The protein must then be packaged for transport to the location where it is needed. After it is no longer needed or breaks down, the components are eliminated or recycled. Put the cellular organelles in the order in which they are needed in the life of a protein.
