Is it possible to take advantage of microorganism's sophisticated makeup, short doubling times and cheap growth media to mass produce medically and commercially useful proteins? This is possible with a few simple genetic manipulations....

Scientific article explaining what natural selection is, and how it manifests itself through genetics and from generation to generation. Natural selection is compared to genetic drift, both of which cause evolution to occur. The limits...

[Free Registration/Login may be required to access all resource tools.] While building on the study of genetics, students will understand how to predict genetic traits with the application of Punnett Squares.

This lecture covers the topic of life now and into the future, including the role genetic engineering will play.

[Free Registration/Login may be required to access all resource tools.] Students will explore the factors that lead to evolution such as genetic mutation, gene drift and gene flow.

Which dictates our existence? Is it our genetic makeup or the environment we grow up in? Kevin Davies offers an update on this long-standing debate, from the NOVA: "Cracking the Code of Life" Web site.

Genetic traits are described as homozygous or heterozygous based on allele similarity. Homozygosity and heterozygosity are explained in this resource. Includes a chart highlighting their differences and some examples that occur in humans.

Discusses the positive and negative aspects and repercussions of genetic cloning.

At this site see an online visual of meiosis, fertilization, and inheritance and play a game.

Georgetown University site with a lengthy article on many aspects of gene therapy. Includes background and historical information and numerous resources on the topic. Focus here is on the ethics of these types of therapies.

Learn how the genes inherited from two parents can be recombined in their offspring in this simulation activity. In addition, investigate the probabilities of passing on inherited genetic disorders.

[Free Registration/Login may be required to access all resource tools.] Describes three of the four forces of evolution: mutation, gene flow, and genetic drift.

Take this interactive, multiple-choice quiz over ecological biodiversity, then review your score and any missed questions at the end.

A start codon is a nucleotide triplet in a genetic sequence that occurs at the start of a protein's synthesis. Read about how this works and how a mutation can sometimes occur.

The DNA in our cells contains our "blueprints," but it's the proteins in our cells that do most of the work. The Human Genome Project has allowed us to start reading the blueprints, but we still don't understand what most of the proteins...

Imagine that a biologist arrived at your big family reunion and had no idea who were sisters, cousins, aunts, uncles, etc., but tried to sort it out by how all of you look. Just based on how you look, would s/he be able to guess whether...

Remember going to the doctor and getting vaccine shots? It's no fun getting poked with a needle, but fortunately, a vaccine gives you protection against a serious illness for years to come. This project will show you why.

Imagine that a biologist arrived at your big family reunion and had no idea who were sisters, cousins, aunts, uncles, etc., but tried to sort it out by how all of you look. Just based on how you look, would s/he be able to guess whether...

This is a project about the "molecular alphabet" of DNA. With just four "letters," it manages to keep track of the plan for an entire person, and keep a complete copy in nearly every cell. This project will help you start learning this...

Simple family tree showing how traits are passed through the family tree.

Use this simulator to obtain a particular species of frog through crossing.

Cross different types of peas and study the phenotype and the genotype of the offspring.

Cryopreservation-storing seeds in ultra-cold liquid nitrogen-is one method for maintaining plant genetic stocks in seed banks. The purpose of this project is to observe the characteristics and outcomes of cryogenically frozen seedlings...

Explains what genetic mutation is, results of mutation, types, how scientists use it in research and in medicine, what it looks like at the molecular level, chemicals that can cause mutation, and frequency of occurrence. (Published:...
