Why DNA in ancient ice might tell us how life on earth DIDN'T start! Learn from an audio lecture that if bacteria were to have arrived on Earth riding on a comet or asteroid, the DNA of the organisms would likely have been too corrupted...

Ira talks with artists incorporating DNA and genetics into their artworks.

Learn all about deoxyribonucleic acid, otherwise known as DNA, through this rap song.

This lesson will introduce genetics, and explore the role of DNA in inheritance. It is 3 of 6 in the series titled "Genetics."

This lesson identify the structure and function of nucleic acids.

Explains how DNA contains genetic material and how it is housed in chromosomes. This lesson is 3 of 5 in the series titled "DNA."

This lesson will discuss the structure and function of the nucleus. It is 1 of 5 in the series titled "Nucleus."

"All DNA evidence is not created equal," says Greg Hampikian, Director of the Idaho Innocence Project. He'll tell us why DNA 'evidence' sometimes leads to the wrong conclusion in this audio lecture. [12:18]

If all the world's information were encoded as DNA, it would fit in the back of a station wagon.

In this video, Paul Andersen explains the importance of DNA is organisms. DNA contains the blueprint for each organisms. The DNA codes for the mRNA which creates proteins. The DNA also is the unit of inheritance which is passed from...

Paul Andersen introduces the nucleic acids of life; RNA and DNA. He details the history of DNA from Griffith, to Avery, to Hershey and finally to Watson and Crick. He also details the difference between prokaryotic and eukaryotic...

Paul Andersen shows you how to compare DNA sequences to understand evolutionary relationships. He starts with a brief introduction to cladograms and evolutionary relationships. He shows you how to classify DNA relationships using a...

Paul Andersen explains how the central dogma of biology explains life on our planet. He starts with a brief discussion of common characteristics of all life. He then explains how DNA is used to make proteins which in turn make you.

Paul Andersen explains the central dogma of biology. He explains how genes in the DNA are converted to mRNA through the process of transcription. He then explains how ribosomes use this message to convert the mRNA to a functioning protein.

Paul Andersen describes the molecular structure of DNA. He describes the major parts of a nucleotide and explains how they are assembled into a nucleic acid. The nitrogenous base, deoxyribose sugar and phosphate group make up a single...

Paul Andersen continues his description of DNA and RNA. He begins with the structure of DNA and RNA and moves into the process of DNA Replication. He also describes the central dogma of biology explaining how DNA is transcribed to mRNA...
