How many times can you say deoxyribonucleic acid fast? Viewers learn the components that create DNA using a video representation. The narrator introduces learners to adenine, guanine, cytosine, and thymine and how they create the...

While our bodies have incredible capabilities to repair damage, some mutations accumulate and lead to disease. Follow the life of a DNA mutation using a computer-generated animation. The narrator explains the impact of radiation,...

Just when things get heated up, they cool down again! Using an animation, a video presentation demonstrates the process of polymerase chain reaction. A narrator describes the temperature changes and the process that ensues as...

Explore the beginnings of the theory to explain DNA replication using an eye-catching animation. Scholars view a simple rendition of DNA replication with an explanation of the first theories suggesting its existence. The animation shows...

Animations are powerful tools for seeing things the eye cannot! A thorough lesson demonstration models DNA replication with a 3-D animation. The video demonstrates how enzymes first separate the original DNA and then copy the resulting...

Genetic code for amino acids always uses three letters. The explanation for why it occurs in triplets makes for a brief statistical video. Examples of single and double letter codes prove insufficient for the number of amino acids.

Finally, something that is better when it's broken! Computers make sequencing short pieces of genome an easy task, yet they struggle with long sequences. Learn about one method for sequencing genomes by breaking it into smaller pieces...

Fred Sanger created the first method of sequencing DNA in 1977 using chemical alterations. Learn more about the Sanger method with a brief animation demonstrating the replication, ordering, and piecing together steps in the process.

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...

When you think of secret messages and data storage, DNA doesn't normally come to mind. Viewers watch a video that explains how scientists use DNA to store information. It describes some recent advances in the area.

Why do some people look young at age 60 while others look old at age 30? Elizabeth Blackburn discovered it is all related to telomeres and telomerase. Her discoveries have not only led to a better understanding of aging, but also to a...

Through the mapping of the DNA of songbirds, scientists have discovered a gene network common among the species. In the video, scholars explore the comparison of DNA sequences, then attempt to place DNA sequences on a cladogram. They see...

The world of genetics and DNA is much clearer than it was 25 years ago, in large part due to the success of the Human Genome Project. Watch a short, engaging video about the dueling organizations who raced to be the first to sequence the...

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...

The topic of this video module is how to classify animals based on how closely related they are. The main learning objective is that students will learn how to make phylogenetic trees based on both physical characteristics and on DNA...

Once the structure of DNA was discovered, the next challenge was determining how the sequence of letters coded for the 20 amino acids could make protein. In theory, one or two letters can only code for 4 or 16 amino acids, respectively....

A video that shows the similarities and dissimilarities between human's and chimpanzee's DNA by examining the DNA sequence code. [2:14]
