Chapter 17 From Gene to Protein Overview: The Flow of Genetic Information The information content of DNA is in the form of specific sequences of nucleotides The DNA inherited by an organism leads to specific traits by dictating the synthesis of proteins Proteins are the links between genotype and phenotype Gene expression, the process by which DNA directs protein synthesis, includes two stages: transcription and translation Copyright ? 2008 Pearson Education Inc., publishing as Pearson Benjamin Cummings Fig. 17-1 Concept 17.1: Genes specify proteins via transcription and translation How was the fundamental relationship between genes and proteins discovered?

Endomembrane System This system controls the process of making proteins specified by the DNA in the nucleus and includes the organelles of the smooth ER, rough ER, and golgi apparatus. *Although ribosomes make proteins, it is not included in this system because it is not a membrane bound organelle and just composed of RNA and proteins.

Ch 6: A Tour of the Cell Concept 6.2: Eukaryotic cells have internal membranes that compartmentalize their functions The basic structural and functional unit of every organism is one of two types of cells: prokaryotic or eukaryotic Only organisms of the domains Bacteria and Archaea consist of prokaryotic cells Protists, fungi, animals, and plants all consist of eukaryotic cells Overview: The Fundamental Units of Life All organisms are made of cells The cell is the simplest collection of matter that can be alive Cell structure is correlated to cellular function All cells are related by their descent from earlier cells Comparing Prokaryotic and Eukaryotic Cells Basic features of all cells: Plasma membrane Semifluid substance called cytosol Chromosomes (carry genes)

AP Biology Reading Guide Chapter 6: A Tour of the Cell Fred and Theresa Holtzclaw Copyright ? 2010 Pearson Education, Inc. - 1 - Name_______________________Period___________ Chapter 6: A Tour of the Cell Concept 6.1 To study cells, biologists use microscopes and the tools of biochemistry 1. The study of cells has been limited by their small size, and so they were not seen and described until 1665, when Robert Hooke first looked at dead cells from an oak tree. His contemporary, Anton van Leeuwenhoek, crafted lenses; and with the improvements in optical aids, a new world was opened. Magnification and resolving power limit what can be seen. Explain the difference.

The Cell The cell is one of the most important concepts in biology since every living organism is made of cells. Bacteria are single celled while you are made up of trillions of cells. As different as we are from bacteria, our cells share some important similarities. All cells have a cell membrane that separates them from the outside environment and all cells have ribosomes where proteins are made. Attribution-Noncommercial 3.0 United States, more free study guides at www.Biology101.org, copyright Anthony D'Onofrio a quick overview The basic diagram of the cell shown above represents most eukaryotic cells (humans, plants, fungi). One main distinction is that plants have a cell wall outside the cell membrane that animal cells lack.
