Upper level discussion of several of Mendel's experiments and laws.

Part of a site on genetics, this page explores DNA as a forensic science. Explains how and why DNA can be used to convict or acquit a criminal from wrongdoing using forensic DNA analysis. Teacher resources too.

Explains basic genetics concepts, including genes, DNA, chromosomes, sex chromosomes, how traits are inherited, genetic variation, cloning, and stem cells.

This comprehensive study guide covers the main terms and concepts needed for a unit on human chromosomes and genes.

Chromosomes carry genetic information in a molecule called DNA. A type of cell division called mitosis ensures that when a cell divides each new cell produced has the same genetic information.

Provides detailed explanation of DNA's structure and function. Includes illustrations.

This interactive lab will enhance learning about DNA by virtually translating a gene.
