DNA Mutation Simulation Access the simulation at: https:/www. biologycorner. com/worksheets/DNA-sim. html

1) Transcribe and Translate your original DNA. Review those terms and write a short definition

Transcription:

Translation:

2) Identify the major players shown in the simulation: MRNA, Codon, Amino Acid, tRNA, anticodon, ribosome. Use the figure below to label these parts.

U с G

3. When the protein is completed, write the sequence of amino acids shown, there are 11. (Hint: click the "stop" button to make the model stop jiggling.)

4. Click on the edit DNA, you will now see the original sequence used to make the protein.

5. Edit the DNA by changing all of the first triplet to AAA Check the new protein created by your new DNA. Describe how this changed the protein.

6. Return the triplet to its original state (ATG). Now place an additional A after the G. your strand will read ATGA. Check the new protein created by your new DNA. Describe how this changed the protein.

7. Return the triplet to its original state (ATG). Now change the second triplet from CCA to CCC Check the new protein created by your new DNA. Describe how this changed the protein.

8. First, you created a POINT mutation in your DNA. DescrIbe what a point mutation is an how this can alfect

the protein created by the gene.
