Get up close and personal with DNA! A two-part hands-on activity has learners extract DNA from a small organism and then their own cheek cells. Scholars then explore DNA replication using questions to guide their analyses.

Investigate how the genetic code on a DNA strands controls what protein is produced with this collection of animations and 3D models. Explore an interactive 3D model of the double helix, watch an animation of transcription, and see the...

Students reinforce their knowledge that DNA is the genetic material for all living things by modeling it using toothpicks and gumdrops that represent the four biochemicals (adenine, thiamine, guanine, and cytosine) that pair with each...
