The DNA in just one of your cells gets damaged tens of thousands of times per day. Because DNA provides the blueprint for the proteins your cells need to function, this damage can cause serious issues-including cancer. Fortunately, your...

This video explains how DNA works and what it does, relating it to an instruction manual for building an organism. [4:29] Followed by a short quiz and a list of additional resources to explore.

Explore stretching just a single strand of DNA using optical tweezers or fluid flow. Experiment with the forces involved and measure the relationship between the stretched DNA length and the force required to keep it stretched.

Explore the molecular structure of DNA in this article. Learn about the components of DNA: nucleotide, nitrogenous base, and phosphate.

A learning module where students can learn about the structure and function of DNA. Interactive activities will explore DNA transcription.

[Free Registration/Login may be required to access all resource tools.] Informational text and video clips about DNA repair. After reading the text, review the key vocabulary terms and answer review questions.

Investigate how the genetic code on a DNA strands controls what protein is produced with this collection of animations and 3D models. Explore an interactive 3D model of the double helix, watch an animation of transcription, and see the...

This curriculum guide assists in filtering through the vast available resources from BioInteractive and HHMI and organizes the material according to various topics related to DNA, including DNA structure, replication, and repair.

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

At DNA from the Beginning, choose from classical genetics, molecules of genetics, genetic organization and control. Each concept is explained through animation, an image gallery, video interviews, biographies and links.

How is DNA evidence analyzed? What makes DNA evidence unique? This comprehensive interactive tutorial explores how old or degraded samples can be analyzed for DNA as well as how DNA profiles are stored.

A nice tutorial on DNA structure. The menu at the bottom allows you to view some different information.

This 51-page booklet is an excellent collection of activities for 11- to 14-year-olds to teach them about DNA. It was designed by Dr Sue Assinder, a molecular geneticist.

Teacher resource page provides links to additional teacher materials, the six units, student worksheets and templates that can be used as teachers and students work through the DNA Interactive site.

[Free Registration/Login may be required to access all resource tools.] DNA is the genetic material in your cells passed on to you from your parents and determines your characteristics. Learn about transformation and how DNA was...

Students conduct their own research to discover and understand the methods designed by engineers and used by scientists to analyze or validate the molecular structure of DNA, proteins and enzymes, as well as basic information about gel...

As a class, students work through an example showing how DNA provides the "recipe" for making our body proteins. They see how the pattern of nucleotide bases (adenine, thymine, guanine, cytosine) forms the double helix ladder shape of...

The link will list a variety of topics about genetics. Click on topic 17 for a very good tutorial on the discovery of DNA. Click along the bottom margin for the different screens.

Recombinant DNA technology has made it possible to gain insight into how genes work. This concept is further developed in this article with an animated explanation, art gallery, audio/video interviews, biographies, and an interactive...

In this online mini-course learners distinguish between the structure, functions, and processes involved with DNA and RNA.

Discover how the structure of DNA relates to its hereditary function in these videos from the American Masters film Decoding Watson. The first video, "DNA Structure and Function," [2:07] can be used with all middle and high school...

This activity explores the equilibrium of dyes that self-assemble into DNA templates. Students use knowledge of equilibrium and quantitative spectroscopy to explore different dyes that bind selectively to DNA molecules. In this activity,...

Outlines the history of the scientific efforts that went into the discovery and mapping of the structure of DNA, spanning one hundred forty years.

[Free Registration/Login may be required to access all resource tools.] Students can watch a video, read some informational text and key vocabulary terms, and answer review questions about the structure of DNA.
