What is Mutation? - Read about mutations and answer the following questions.
  1. What is mutation?
  2. What is the most common error/mutation in DNA?
  3. Describe other errors/mutations that might occur in DNA?
  4. When will an error/mutation be passed on to an organism's offspring?
  5. Why do most mutations have no effect?
  6. How can a mutation be an advantage, or be useful to an organism?
  7. What are some examples of variations that are neither good nor bad in humans?
  8. What are the environmental agents that can cause mutations?
  9. What might happen if the cell's DNA repair machines cannot fix DNA mutation/damage?
Transcribe and Translate a Gene -  One question...answer it after you have finished the interactive.
  1. How is it that there can be so many different proteins, when there are only 20 different amino acids?
 
Protein Synthesis Interactive - Answer the following questions while going through the simple tutorial.
  1. What is responsible for "Unzipping" the DNA molecule?
  2. Use the RNA bases on the left and pair them up with the DNA.  What RNA base pairs with A?  What DNA base does RNA not have?
  3. What is the RNA called that takes the message from DNA?
  4. What do we call the code of 3 letters on mRNA?
  5. What type of RNA brings the amino acid to the ribosome?
  6. When does protein synthesis end?
