Modeling DNA Structure, Replication, & Protein Synthesis Exercise

Name: .

Before coming to labs carefully read the previous pages on DNA Structure, DNA Replication, DNA Transcription, and RNA Translation then answer these pre-lab questions.Be prepared to hand in your responses to the pre-lab questions at the start of lab.

  • Explain how it is possible for you to have so many different kinds of cells in your body (e.g.
  • Explain in your own words your understanding of the central dogma of biology.
  • Answer each of the following questions.
    • What is the primary structure of a protein?
    • Of what importance is the primary structure of a protein?
    • What ultimately determines the primary structure of a protein?
    • What is a mutation?During what process are mutations most likely to occur?
    • Why do mutations affect the primary structure of a protein?
  • Describe in your own words the structure of DNA.
  • Describe in your own words how DNA makes copies of itself. (I.e. Describe DNA
  • Protein synthesis involves two processes, transcription and translation. Describe in your
