5. 5 DNA Deoxyribonucleic acid. Contains the instructions needed to make proteins that perform important functions for an organism (examples: develop, survive and reproduce).

6. 6 RNA Ribonucleic acid. Carries the genetic instructions from DNA in nucleus to cytoplasm where proteins are made. (Image from http://www.biologycorner.com/resources/mRNA-colored.gif )http://www.biologycorner.com/resources/mRNA-colored.gif

7. 7 Cell Membrane (Plasma Membrane) Surrounds the cell. Controls what can come into or leave the cell.
