A mutation in the gene encoding for the myostatin protein causes extreme muscle growth in some animals, such as the Whippet shown on the right. Genetic engineers alter the DNA of organisms to change properties or traits by modifying the proteins that are produced from the DNA. These changes take place in a controlled manner to reduce the likelihood of errors occurring, but even being careful is not always enough to prevent mistakes and unwanted results. Sometimes DNA spontaneously mutates when replicating, such as when researchers try to grow many bacteria from a single modified version.
It is important to understand how mutations occur and the unintended effects they may have on the outcome of DNA modification. Engineers often use models to simplify complex processes; in this activity, students model how DNA can mutate using an easy-to-understand model that illustrates that errors can occur and where. Each TeachEngineering lesson or activity is correlated to one or more K science, technology, engineering or math STEM educational standards.
In the ASN, standards are hierarchically structured: first by source; e. Develop and use a model to describe why structural changes to genes mutations located on chromosomes may affect proteins and may result in harmful, beneficial, or neutral effects to the structure and function of the organism.

View aligned curriculum. Students learn about mutations to both DNA and chromosomes, and uncontrolled changes to the genetic code. They are introduced to small-scale mutations substitutions, deletions and insertions and large-scale mutations deletion duplications, inversions, insertions, translocations and nondisjunction Students learn how engineers apply their understanding of DNA to manipulate specific genes to produce desired traits, and how engineers have used this practice to address current problems facing humanity.
Students fill out a flow chart to list the methods to modify genes to create GMOs and example a Students should have an understanding of the relationship between DNA and proteins and how a cell makes proteins from DNA. This activity focuses on small-scale mutations, so a basic knowledge of the differences between small- and large-scale mutations is important, which can be learned by conducting the associated lesson, All Sorts of Mutations: Changes in the Genetic Code.
Who can tell me how the X-Men got their powers? We call them mutants, but what does that really mean? It means that they are still considered humans, but somewhere along the way DNA mutations gave them some powers. Answer: They change the proteins that cells produce. Of course, a single mutation in DNA would not really cause such a drastic change in abilities or appearance.
Today we will perform two activities to show how these mutations can occur and illustrate the possible effects of different mutations. Figure 1. Example mutations. The first line represents a set of initial instructions. The other lines show some possible mutations that could occur during the telephone activity. Abbreviation for deoxyribonucleic acid. Mutation Identification: During each round of the Part 1 activity, have students identify what mutations types occurred in the instructions.
Predator Discussion : After Part 2 of the activity, as a class, have students share and compare their experiences with and conclusions from the predator game, as described in the Procedure section. Worksheet : Have students complete the Mutation Telephone Worksheet to review the concepts covered in the activity.
Review student answers to gauge their depth of comprehension of the activity concepts.

This game, and others like it, can be used to teach students how evolution works.
