Exploring Structures: DNA

In this activity, learners create a necklace of wheat germ DNA. Learners add alcohol to wheat germ so that the DNA clumps together. Use this activity to talk about how self-assembly is a process by which molecules and cells form themselves into functional structures. Safety note: do not allow learners to ingest any of the materials!
