Everything evolved from a common ancestor, but how did modern plants and animals develop so many more genes? Scholars use an online interactive to learn about the process. They begin to understand common genes with an animation, multiple...

All human infants are lactose tolerant, yet some adults are lactose intolerant—why is that? Individuals discover the process of gene mutation through a study of the lactase gene (LCT). They understand the geographic connections,...

Very few universities still offer a master's degree in the ecology of grasses, but that was the degree that led George Wells Beadle to an interest in genetics and later a Nobel Prize. Scholars learn about the discoveries of Dr. Beadle...

Have you ever been so tired you missed a major announcement? Eric Wieschaus woke to a call explaining he won the Nobel Prize, but he thought it was just a dream until Christiane Nusslein-Volhard, a co-winner, explained it to him later...

Scientists work every day to find solutions to genetic diseases. Scholars learn about the process of gene sequencing, mutations, and the results. They explore genetic diseases and therapies to intervene and help and, through case...

Biotechnology changes lives every day, but how did it all start? Learn about Cohen and Boyer's technique for recombinant DNA and the founding of this new scientific study. Then, scholars use the online interactive to discover how Hanahan...

Mario Capecchi requested funding for a new procedure targeting genes and was rejected. Four years later, after he proved it worked, the NIH apologized and funded his research. Use an online interactive to learn about his research and the...

Connect Mendelian genetics with Darwinian theories. An interactive lesson lets pupils explore how George Shull used research from other scientists to explore genetic variation. The resource outlines the statistical analysis of genetic...

Does natural light damage or repair DNA? Learn the answer discover the scientists who researched the topic with an online interactive. Scholars read through an online animation presenting the content at their own pace. Then, they read...

Are all academicians allured with alliteration? Use this cross-curricular online resource to simultaneously expose your scholars to parts of speech and the genetic mutation causing albinism. Initial context gives students an introduction...

Build a gene network. The lac operon is a set of genes which are responsible for the metabolism of lactose in some bacterial cells. Explore the effects of mutations within the lac operon by adding or removing genes from the DNA.

Mutation is a process that changes a DNA sequence. But how does a difference in a gene's DNA sequence (or genotype) lead to a difference in an observable trait (or phenotype)?

This unit discusses the following topics: cloning, transgenic, gene therapy, genetic code, human genome and DNA replication. It contains 19 interactive activities.
