During transcription in a eukaryotic cell, a segment of DNA known as a gene opens up, and a copy of it is made, called a messenger RNA (mRNA). The mRNA leaves the nucleus through the . Once it leaves the nucleus, the mRNA enters the organelle adjacent to the nucleus, known as the .At this point, the mRNA is recopied into tranfer RNA (tRNA). In the process of translation, the tRNA becomes attached to the and synthesizes a protein. That protein gets packaged up and leaves through a circular organelle, know as a and travels to the cis-face of the , where the protein is modified, stored and eventually leaves from the trans face. The protein is used within the cell and eventually loses its functionality and ends up being digested by a circular organelle, the in a process known as phagocytosis.
