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...

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...

The DNA double helix contains two sequences of nucleotide code letters than run along the molecule. Untwist the spiral and DNA can be seen as two parallel strands. That's why its sometimes called the double helix. Unzip the strands and...

A description of how the triple-helix DNA model was a precursor to the accepted double-helix model of our DNA. [0:27]

[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.

A great resource for the history of the discovery of DNA! This website includes over 300 documents, photographs, audio clips, and video excerpts that documents how the double helix structure was discovered.

Students reinforce their knowledge that DNA is the genetic material for all living things by modeling it using toothpicks and gumdrops that represent the four biochemicals (adenine, thiamine, guanine, and cytosine) that pair with each...

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

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 article describes the race to unlock the mystery of life by determining the double helix structure of the DNA molecule. The discovery of DNA and its structure is an example of collective learning.

Read a letter that Francis Crick wrote to his son shortly before Crick and Watson published their findings about the structure of DNA. In the letter, Crick clearly describes how the double helix structure works.

Test your knowledge of the history of DNA and the discovery of the double helix model in this twenty-question trivia quiz.

[Free Registration/Login may be required to access all resource tools.] DNA is located in the nucleus. Proteins are made on ribosomes in the cytoplasm. Remember that information in a gene is converted into mRNA, which carries 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 site is provided for by DNA Interactive. The genome is the entire endowment of genetic information. It is the "Book of life," on an organism. This site demonstrates the methods used to map and sequence the human genome and to...

Once the code was discovered, how could DNA be manipulated, what tools would be needed to make use of DNA. These are some questions answered in this interactive website.

Access Excellence provides an excellent graphic showing the structure of the DNA molecule and its components.

Retrace the development of our knowledge of nucleic acids by viewing pictures of nucleic acids (both DNA and RNA) taken in 1952, 1973, 1979, 1980, 1984 and 2001.

Examples of using DNA for forensic purposes is discussed here, as well as uses to unravel historical puzzles, trace the history of a species and answer health problems.

Take an interactive quiz over DNA. After completing the quiz, check your score, and then revisit any incorrect question for further review.

A transcript of a personal interview with Francis Crick, the co-discoverer of the structure of DNA.

[Free Registration/Login may be required to access all resource tools.] Covers the structure and function of nucleic acids.

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

This is a basic animation of how DNA is structured.
