Two French scientists describe the research they did to figure out how bacteria turn certain genes on and off. The topic is a little involved, but the animations should help you understand the process.
This multimedia article includes animations, pictures, video, biographical information, and quiz questions that are accessed by clicking on buttons along the bottom of the page. Here you can see how common genes are evidence for common ancestors.
Early research showed that genes code for proteins. This was based on studies using mutant strains of bread mold. This multimedia article includes animations, pictures, video, biographical information, and quiz questions that are accessed by clicking on buttons along the bottom of the page.
This collection of publications about genetics includes a unique approach to illustrate a genetics timeline. Important genetic events are correlated with other historical events. The book format allows you to scroll through history.
The development of creatures that appear to have nothing in common is directed by a surprisingly small number of genes. In this video segment, learn about the power of master control genes. Footage from The Secret of Life: "Birth, Sex & Death." [2:58]
This site from the University of Arizona runs a two-step simulation of Genetic Drift. There are teacher's notes included. A great site to aid in understanding Genetic Drift.
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.
Get it all straight! The "Tour of the Basics" will help clarify the basic principals of genetics science from DNA, genes, chromosomes, proteins, heredity, and traits.
Genes are instruction manuals for our bodies and are contained in DNA. This video describes how genes make us unique.
The shared set of genes for body segments, possessed by all animals, are discussed in this video segment from Evolution: "Great Transformations."
The Geniverse software is being developed as part of a five-year research project funded by the National Science Foundation. Still in its early stages, a Beta version of the software is currently being piloted in six schools throughout New England. We invite you to try the current Beta version, keeping in mind that you may encounter errors or pages that are not fully functional. If you encounter any problem, it may help to refresh or reload the web page.
This narrated animation from Interactive NOVA: "The Secret of Life" illustrates DNA replication.
The Genetics Student Edition book is one of ten volumes making up the Human Biology curriculum, an interdisciplinary and inquiry-based approach to the study of life science.
Explains the goals of the Human Genome Project. It also explains some of the ethical, legal and social challenges associated with this new technology.
The human genome serves as an instruction manual for life, with its own distinct letters, alphabet, sentences and chapters. Learn about the genome, nucleotides, DNA and genes with this interactive lesson.
This cell biology lesson explains and illustrated the different phases of meiosis. Includes vocabulary and assessment links as well as othe related resources.
This initial module from the GENIQUEST project introduces the dragons and the inheritance of their traits, then delves into meiosis and its relationship to inherited traits. Students examine the effects of choosing different gametes on dragon offspring, and learn about genetic recombination by creating recombination events to generate specific offspring from two given parent dragons. Students learn about inbred strains and breed an inbred strain of dragons themselves.
This video segment describes the role of the sickle cell gene in natural selection. Footage courtesy of the PBS series Secret of Life: "Accidents of Creation." [4:49]
Discover how mitochondrial DNA (mtDNA) is inherited, and complete a pedigree chart by determining which individuals might share mtDNA with an unknown ancestor.
This link has many tools to help understand the revolutionary sciences and discoveries in genetics.
