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 [a].  Once it leaves the nucleus, the mRNA enters the organelle adjacent to the nucleus, known as the [b].At this point, the mRNA is recopied into tranfer RNA (tRNA). In the process of translation, the tRNA becomes attached to the [c] and synthesizes a protein. That protein gets packaged up and leaves through a circular organelle, know as a [d] and travels to the cis-face of the  [e], 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 [f] in a process known as phagocytosis. 

Which evidence supports the endosymbiotic hypothesis for the origin of the mitochondrion?

What is the advantage of the the origin of the nucleus according to the leading hypothesis?

Nearly all mushrooms are made up of this group of fungi.

Angiosperms are most closely related to _______.

 Evergreens are more advantageous in the tiaga due to the fact that they retain their leaves all year round. In this manner, they are able to photosynthesize immediately when the temperature gets above freezing.

Which feature did the first eukaryotes probably lack?

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?

Life originated in which eon?

Cell walls of fungi are composed primarily of
