DNA & Genes
Describe the double helix structure of DNA (base pairs, complementarity), explain how genes are sections of DNA that code for proteins, introduce the central dogma (DNA → mRNA → protein) conceptually, and discuss the ethical implications of CRISPR gene editing — including potential benefits (genetic disease treatment) and concerns (germline editing, 'designer babies')
Typical age: 12–14 years
“If your child heard that scientists have edited a human gene to prevent a hereditary disease, could they explain what DNA actually is, how genes work, and why some people think editing human DNA raises serious ethical questions?”
