DNA—From Genes to Proteins, Third Edition

Grades 6 - 8

Modeling activities combine with microslide images to help students decipher the codes of life. Students trace the characteristics of their own features to proteins, and then even further to the genetic material inside the nucleus in every cell in their bodies. Students identify cell structures and functions, and the chromosomes and genes that determine unique traits. Using base-pair models of double-helix DNA molecules, they explore DNA replication and DNA transcription to messenger RNA. They investigate how and where mutations can occur and compare human cells to bacteria and virus cells. Then, the perspective changes, and students consider some cutting-edge applications of biotechnology: genetic engineering, DNA fingerprinting, and the Human Genome Project. (13 Activities)
