Opening Activity April 18, 2017 From our protein network practice, how are proteins and traits related. Give an example. How are the building blocks of DNA and Proteins different? I can… Explain the relationship between DNA, proteins, traits. Homework: All 3rd quarter assignments due TODAY!! (NB, Lab Reports, etc.) Enzyme Quiz Thursday 4/20 Biotech Test Retake Mon-Wed during HR

“Cereal Protein” Review How did your protein compare at your table? Write down in your journal, what did the following represent: Flexspace? Construction area? Individual cereal pieces? The code to build your protein? How did you get the message to the construction area?

“Cereal Protein” Review How did your protein compare at your table? Write down in your journal, what did the following represent: (answers in parenthesis) Flexspace? (nucleus) Construction area? (Ribosome – organelle, site of protein synthesis) Individual cereal pieces? (amino acids) The code to build your protein? (gene) How did you get the message to the construction area? (use first letter of the word, number or symbol code – Our cells use a molecule called RNA to transfer the information from nucleus to cysoplasm)

DNA  Protein Practice Directions for using a codon wheel: 1st DNA base  Find the letter in the center of the wheel. 2nd DNA base  Find the letter in the second layer of the wheel. 3rd DNA base  Find the letter in the outer layer of the wheel
