Enzymes proofread DNA, reducing the error rate to one in one billion base pairs. Learn about the important process and so much more with the help of a presentation. It opens with the history of DNA and the major scientific contributions...

Frederick Sanger won two Nobel prizes for protein sequencing and DNA sequencing. Young scientists learn about Dr. Sanger's research and amazing discoveries. They read an article and a biography, view videos and animations, and apply...

How do viruses hijack our cells to produce more viral particles? Junior immunologists model how viral RNA integrates into a host cell's DNA using pop beads and use interactive tools to explore a virus' genome. The teacher's guide...

The experiment known as one of the most beautiful experiments in biology changed the way we think about DNA. Learn about the experiment and the scientists who designed it—as well as the scientists who built on the results—with an online...

How do doctors fight a virus that's constantly mutating? Show science scholars how we fight HIV using one of its own most fundamental processes through a thoughtful demonstration. The lesson focuses on how protease inhibitors prevent HIV...

Teach young biologists the language of life with this series of worksheets on DNA. By working through these pages, students expand their understanding of genetics as they learn about the process of transcription and the...

Where is a geneticist's favorite place to swim? A gene pool. Young geneticists complete hands-on activities, experiments, and real-world problem solving throughout the unit. With extra focus on dominant and recessive genes, Punnett...

This is a 5-question quiz based on the passage "The "Speed Limit" of DNA Polymerase."

A good tutorial on replication. The menu bar at the top provides more history, background and animations.

[Free Registration/Login may be required to access all resource tools.] This concise article complete with labeled diagrams, key vocabulary terms, and review questions illustrates DNA replication.

Read a passage about kinetics and DNA replication and answer the follow-up questions.

Two multiple-choice quizzes, one on the processes and types of biological molecules, the other on the structure and replication of DNA.

[Free Registration/Login may be required to access all resource tools.] The process of DNA replication is not always 100% accurate. Sometimes the wrong base is inserted in the new strand of DNA. This wrong base could become permanent. A...
