Unit 10 - DNA,RNA and Protein Synthesis

In the previous unit we saw the importance of the nucleus and its DNA in cell reproduction. In this we will take a closer look at the structure of DNA and the basis for its "genetic code." In addition, we will examine the similarities and differences between DNA and RNA and then learn how both DNA and RNA work together to synthesis the proteins that ultimately express the genetic code in DNA as traits in a living organism.

Instruction this week will direct instruction supplemented by several activities, worksheets, a project, and a play.

SB2a: Distinguish between DNA and RNA.
SB2b: Explain the role of DNA in storing and transmitting cellular information.

Assignment 1: The Structure of DNA and DNA Replication - mini lecture. Take notes and complete appropriate parts of the DNA, RNA, Protein Synthesis worksheet as you go. (Click here to see worksheet)

The following short video summarizes what you have learned about the structure of DNA and how DNA replicates:



Assignment 2: Acquire a basic understanding of how DNA holds and transmits cellular information by completing the following activity.

• Access an interactive website called "Tour of the Basics". Then, click on the tab at the top of the page entitled "What is DNA?" Work through this short presentation. Discuss what you learned with your instructor afterwards. Click here to access the website.
  

Assignment 3: Build a model of a DNA molecule. To complete this project, you will work together in class in small groups of 3-4 students. Each group will build a portion of the molecule. Later, we will connect the sections together. (Click here for instructions)

Assignment 4: How DNA and RNA work together to make proteins. -- mini lecture. Take notes and label the appropriate diagrams on your worksheet as you go.

Watch the following video summarizing what you have learned about DNA, RNA, and protein synthesis:



Assignment 5: Review protein synthesis by completing the following activity. Your goal is to learn how to transcribe and translate genetic code into an amino acid sequence we call a protein.

Assignment 6: Participate in the play -- Protein Synthesis. This is a class activity.
