Genetic Building Blocksby: Ezra Roberg

Journal ArticleDigital resources are stored online in your NSTA Library.

The “Central Dogma” of genetics states that one gene, located in a DNA molecule, is ultimately translated into one protein. As important as this idea is, many teachers shy away from teaching the actual mechanism of gene translation, and many students find the concepts abstract and inaccessible. This article describes a unit that models concepts in a visual and concrete way. The activity has achieved a high degree of success with over 500 ninth- and tenth-grade students at a large urban high school.

I read this article, and created a worksheet for use in my classroom based on the ideas in it. I did modify the activity slightly, but kept the framework and the basic idea, and it is really great! It really seems to work well to get students in the habit of reading the genetic code, and it is a fairly quick mini-lab. Once you have done the initial setup, it takes no time to prep for the class you are doing it in! It is a great idea that is easily modifiable for any learning level!!
