Unformatted text preview: Lecture Module 2c Notes: Protein Synthesis. Eleven multiple-choice questions are assigned to the content of this section. m: l l ”"M Opening screen: Proteins are important biomolecules in ”Hams—r our cells. The DNA contains the genetic codes for the synthesis of all the proteins. Although the DNA is located in l-I-VilII it man-- the nucleus, protein synthesis takes place in cytoplasm. Elm-aw- arm DNA consists of two complementary strands of nucleotides awn-mu- .MHMHMM twisted together to form a double helix. You will see DNA Wm represented in different ways. In the space filling model each 0"“ .EvIrymctsushaldqu-hslixm atom is represented by a small sphere. The ribbon model uses ribbons to represent the sugar backbone of the DNA. The DNA is too precious to be let out of the the nucleus where it is o mun-mu- mnuwmmmdm‘ costlier-ms .mmAbhopncioustoh-htfld ”MW" protected. The code must be transmitted to another molecule " ‘mmmmm” called messenger RNA (mRNA) that can move into the cytoplasm where the actual protein is synthesized. 2.2.? a G0 to the next screen: Here you see the major “players” in the “EM-”w ’ ' ‘ ' ‘ protein synthesis process: The DNA (in the nucleus), rough ER and 5;“; m__,___ the ribosomes (attached to the ER), the smoothlER and the Golgi HES... u-m apparatus.
