Learn about DNA by building a model of its double-strand structure.

An animation introducing the basic concepts of cells, DNA, recessive inheritance, and Punnett squares.

Students use food (licorice and marshmallows or fruit) to make models of DNA.

Take this interactive, multiple-choice quiz over the molecule of life, DNA. Then review your score and any missed questions at the end.

This site from the Acadia University provides the basic structure of DNA and RNA and a decent compare/contrast between the two.

In this activity, students learn the concepts and techniques behind DNA profiling of the national DNA databank. Students will then have the opportunity to collect and interpret actual STR data, and to answer one or more questions.

Family studies are a good way to learn about DNA profiling and RFLP analysis because students can follow the inheritance of DNA markers from one generation to the next. Students have the opportunity to do this in this activity.

Students practice a problem using DNA profile analysis to characterize human DNA samples as applied in paternity analysis and sex crimes investigations.

Students have the opportunity to interpret actual case results from the use of the Restriction Fragment Length Polymorphism (RFLP) method to characterize human DNA samples as applied in paternity analysis and sex crimes investigations.

A decent site that provides a good background to both general DNA structure and replication. Text based outline with links to graphics.

A good site that begins with the background and branches into the structure, function and applications of technology. This version of the page requires Java, and should open some applets that allow you to see the structures in 3-D.

Learn how genetic screening is used to identify people who are healthy genetic carriers for diseases that occur more often in certain populations.

In this lesson plan site, students learn about DNA and examine three different situations where DNA was used to solve a case.

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...

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...

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...

An explanation of genomes in regards to the amount of DNA compared to the number of chromosomes in different organisms. Additional discussion focuses on how the human genome is different from other species.

Illustration of a classic double-helix model of DNA.

New Zealander Maurice Wilkins was a key researcher in the discovery of the structure of DNA. This resource offers a detailed biography of his life and career.

Wilder muses about writing, drama, patriotism and other topics in this interview. Download the interview as a .pdf document, or read a short excerpt online.

In this activity you will learn the concepts and techniques that are part of the DNA profiles.Dictionary - View detailed dictionary

Study proteins and amino acids in the science of biology including how they are made using DNA, transcription, and translation and different types of proteins on this site.

This interactive activity, adapted from the Dolan DNA Learning Center, uses Punnett squares to illustrate Mendel's laws of inheritance and how a particular gene combination results in a 3-to-1 ratio of dominant-to-recessive traits.
