In this lab activity, students analyze the effects of several different types of mutations on a DNA sequence and the subsequent protein produced. To represent the randomness of DNA mutations, a dice is rolled to determine what type of mutation each student receives (substitution, insertion, or deletion of one nucleotide). Students will complete two trials of mutations (first they will mutate the fourth nucleotide, and then the sixth), and compare the outcomes of these trials to determine which one had a more detrimental effect on the amino acid sequence. A complete answer key of all possible mutation outcomes for each trial is included.

This activity is a great way for students to understand the impact of one single nucleotide change on a protein. All you need are some dice!

Distance Learning:

As this activity only requires a six-sided die (which many students have at home from many board games), this can be a great distance learning option! Students can type directly on the document and submit it virtually. If a student does not have a dice at home, instruct them to Google "virtual dice" and they can roll a virtual dice online!

If using Google Classroom, you are provided with a link to a Google Docs version of the lab activity!

This product pairs wonderfully with my guided notes on genetic mutations which can be found HERE! Purchase both resources together as a bundle HERE!
