14. Protein Synthesis
Transcription – synthesis of the mRNA from the DNA in the nucleus.
RNA polymerase – enzyme that assists in obtaining the genetic information.
mRNA leaves the nucleus through the nuclear pores of the envelope.

16. Protein Synthesis
Translation – occurs in the cytoplasm associated with a ribosome (rRNA). The mRNA, tRNA, and rRNA all come together to bind the amino acids together into the proper proteins as dictated by the DNA.
