The Guanine Nucleotide-Binding Switch in Three Dimensions

Guanine nucleotideí˘ŒóŒńbinding proteins regulate a variety of processes, including sensual perception, protein synthesis, various transport processes, and cell growth and differentiation. They act as molecular switches and timers that cycle between inactive guanosine diphosphate (GDP)í˘ŒóŒńbound and active guanosine triphosphate (GTP)í˘ŒóŒńbound states. Recent structural studies show that the switch apparatus itself is a conserved fundamental module but that its regulators and effectors are quite diverse in their structures and modes of interaction. Here we will try to define some underlying principles. (less)

In this activity, learners build edible models of DNA, while learning basic DNA structure and the rules of base pairing. Learners construct the models out of licorice and colored marshmallows and create labels for the base pairs and backbone. This is an excellent activity to use at the end of a unit on DNA. (less)

In this activity, learners identify the DNA base bars guanine, cytosine, thymine and adenine. Learners create a DNA model using colored paper clips to resemble these base pairs. This activity is featured on pp.19-20 (part of a lesson that begins on p.18) of the "Yesterday, Today and Tomorrow: Agricultural Biology" unit of study for grades 6-8. (less)

By building their own DNA model in this OLogy activity, kids learn about the unique genetic code that's found in every cell of their bodies. The activity begins with a brief look at how all living things are made of cells, and what that makes them unique is DNA. Then, using toothpicks, colored paper, and other common supplies, students create a 3-D model of DNA and "do the DNA twist" to make it look like a double spiral. Interspersed throughout the activity are kid-friendly descriptions of the discovery of DNA and where it's found. The experiment ends with additional challenges for students, such as making a DNA mobile with pipe cleaners or some other flexible material. (less)
