Which macromolecules contain a phosphate, sugar and a nitrogenous base?

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. 

 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.

What is the process by which DNA codes for a messenger RNA (mRNA)?

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

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

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

The mycelium of fungi are made up of these long, branching filaments. What are they called? Note: spelling counts.

Cell walls of fungi are composed primarily of
