The Double Helix Nebula, captured in this space telescope image, features a variety of red giants and red supergiants. In addition, a detailed textual overview explains various specifics of the picture.

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

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.

Instructional module focusing on the physical structure of DNA. Discussion incorporates the description of the nucleotides, base pairs, and the double helix shape of a DNA molecule. Site also includes an interactive practice quiz and...

Biographical information about Francis Crick as well as access to an archival collection of his papers, letters, photographs, and notes, including those related to the discovery of the double helix.

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...

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 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.

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...

A vertical image of a DNA double helix.

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 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.

Follow a timeline which describes the discovery of the DNA double helix model in the early part of the 1950s.

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

Learn about the Austrian biochemist and author, Erwin Chargaff, best known for "Chargaff's Rules" which lead to the discovery of DNA's double helix structure.

DNA is the molecule of life, as life's secrets are encoded in DNA. In this interactive activity. we see the famous double helix structure of DNA.

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...

Illustration of a classic double-helix model of DNA.

Video describing the structure and function of the DNA molecule. [4:27] Includes a short quiz and a list of additional resources to explore.

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