What do you have in common with a fruit fly? About 60 percent of your DNA. The resource, divided into two units, is intended for grades four to eight and another for high schoolers. Both units include eight lessons covering the...

What happens when genes change? Junior genetic investigators examine the effects of mutation in the third unit of a four-part Biotechnology series. Individuals discover the types of mutations through a series of PowerPoints, then partner...

Your genome, every human's genome, consists of a unique DNA sequence of A's, T's, C's and G's that tell your cells how to operate. Thanks to technological advances, scientists are now able to know the sequence of letters that makes up an...

Given illustrations or partial DNA sequences, students will identify changes in DNA and the significance of these changes.

Genes are actually a specific sequence of DNA and they have a clear start and stop. Learn about the discovery and sequencing of genes at this site. This multimedia article includes animations, pictures, video, biographical information,...

[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...

Andrea M. Henle examines the science behind gene editing tools such as CRISPR.

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...

This article contains information on how DNA is repaired to prevent mutated damage from interrupting DNA processes.

The human genome project was established to determine the sequence of DNA bases that are found in each human cell. Understanding what the resulting proteins do is an entirely different project. This page is about how we are trying to...

This multimedia article includes animations, pictures, video, biographical information, and quiz questions that are accessed by clicking on buttons along the bottom of the page. The topic is the human genome.

[Free Registration/Login may be required to access all resource tools.] The DNA sequence contains the instructions to place units called amino acids into a specific order. When these amino acid are assembled in that specific order,...

[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...
