You are the lucky student of a wacky professor who develops a time machine and he asks if you will test it with him. You get in and there’s an immediate glitch. The read out indicates that  you have traveled back 80 million years ago, and are now stuck in the Mesozoic era.  Which of the following would you most likely see when you step out of your time machine?

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.
