• Journey into DNA

"Chances are you've seen an illustration of DNA's double-helix structure and even pictures of the chromosomes that comprise the human genome. But where and how does the famous double helix fit into chromosomes, and how do chromosomes relate to the human body? 

This exploration allows you to travel to the tiny world of DNA. Beginning with the body and ending with the atoms that make up a single DNA base, you'll be able to zoom in to 15 different levels to see DNA's relationship to us as a whole. Along the way you'll also see the intricate bending and winding that takes place within a chromosome, which allows more than five feet of DNA to fit within the nucleus of a tiny cell."

What is the Difference between DNA and RNA ?

What is the Difference between DNA and RNA ?




DNA and RNA - Part 1 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 and is finally translated into proteins. He also introduces genetic engineering and explains how transformation is used to create insulin.  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 nucleotide. The 5' and 3' end of DNA is described. The importance of hydrogen bonds in the 3-dimensional shape is also included. with thanks to bozemanbiology

DNA and RNA - Part 1 - 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 chromosomes.

This animation shows how the digital information encoded in DNA directs protein synthesis inside the cell and provides a unique look at the evidence for intelligent design as described in Dr. Stephen C. Meyers book Signature in the Cell
