DNA and Genes

Adaptations must be made as environments change. This fabulous presentation features Icelandic icefish, a transparent, scaleless specimen that even has colorless blood. Genetics and adaptations concepts are explored as scientists study...

Does the human body evolve as quickly as human culture? With a stellar 15-minute video, explore the trait of lactose intolerance. Only about 1/3 of human adults seem to still have the enzyme lactase and therefore, the ability to digest...

A pinch of adenine, a dash of thymine and ta-da, you have life! Well, it's not quite that simple, but through this series of activities and experiments young scientists learn about the structure of DNA and how it contains the recipe for...

Help your class unravel the mystery of DNA with a comprehensive life science presentation. Slide-by-slide this presentation takes young biologist on an exploration of the structure of DNA, its ability to self-replicate, and common...

The many slides and images in this PowerPoint are clear and relevant to the detailed content covering the details of DNA structure, replication, cell differentiation, and mutation on an advanced level. The slideshow summarizes all of the...

When DNA relaxes and unwinds after a long day, it literally unwinds. The presentation includes DNA, DNA replication, genes, multiple experiments that helped us understand DNA, the structure of DNA, and transcription. This is the ninth...

Chromosomes, genes, traits ... how are they all related? A short video introduces the many factors involved in heredity. Junior geneticists explore the transfer of chromosomes from parents to offspring, the proteins created by base pair...

No, you didn't get your genes from the local clothing store. Learn where they really come from by watching this video as it explores how the genes found in all plants and animals today have arisen over billions of years of mutations from...

Introduce biology classes to the structure of DNA, the role of genes, and how mutations occur with this nifty resource. After viewing an animated video, discuss the accompanying Think questions and then explore the myriad of additional...

In humans, the rate of mutation from one generation to the next is between 100 and 200 mutations. Discover the role of DNA mutation in evolution with an enriching lab activity.
