PROTEIN SYNTHESIS - DRY LAB

MOLECULAR GENETICS – 5

PURPOSE – To futher practice the steps that occur in the process of Protein Synthesis.

PROCEDURE –

I. The following is the base sequence on one strand of a DNA molecule:

AATGCCAGTGGTTCGCAC
    1. What is the complementary DNA sequence?__________________________________________
    2. Draw an unwound (ladder like) model of this molecule.

      3.  

       

       

       

    3. What is the base sequence of mRNA that would be transcribed from the strand of DNA given above.

      4. __________________________________________

    4. Draw the mRNA molecule produced.

      5.  

       

       

       

       

    5. The protein coded for in this situation is six Amino Acids long. What is the sequence of these Amino Acids?

      6. __________________________________________

      II. The following is the base sequence on one strand of a DNA molecule:

      AATCCCACTGGTTCGCAC
    6. What is the complementary DNA sequence?__________________________________________
    7. Draw an unwound (ladder like) model of this molecule.

      8.  

       

       

       

    8. What is the base sequence of mRNA that would be transcribed from the strand of DNA given above.

      9. _______________________________________

    9. Draw the mRNA molecule produced.
