Classroom Resources

This multipart activity is designed to give students a firm understanding of genetic profiling using short tandem repeats (STRs), which is a process used by forensics labs around the world.

This interactive module allows students to use DNA profiling and related biological concepts to solve two cases of elephant poaching.

This video describes the technology of metabarcoding, which allows scientists to determine herbivore diets based on the sequences of plant DNA extracted from animal dung.

This video explores how advances in DNA sequencing technology have improved cancer diagnosis and treatment.

This tutorial describes the principles of DNA sequencing and sequence assembly, and shows how they apply to different sequencing techniques.

This tutorial describes how DNA microarrays called Virochips are designed to detect known viruses and discover new ones.

This animation describes how only a small part of the human genome directly codes for proteins.

This animation shows how the Human Genome Project sequenced the human genome, which contains over 3 billion nucleotides.

This animation illustrates Sanger sequencing, one of the earliest methods used to sequence DNA.

This animation illustrates shotgun sequencing, a method that was used to sequence the human genome.

This animation describes how many nucleotides encode a single amino acid, which is a key part of the genetic code.

This tutorial explains how scientists analyze and interpret the large data sets generated by DNA microarrays.
