DNA versus RNA

Five percent of the weight of a human cell comes from RNA, while only one percent comes from DNA. The video explains what RNA is and how it relates to DNA. It also describes the importance of understanding RNA and the two types of RNA:...

Every single cell in the human body is packed with genetic material! A video presentation provides a thorough overview of the components of this genetic material. An engaging instructor defines DNA and RNA and discusses its structure and...

Warning: there are no lifeguards in the gene pool! An educational video compares and contrasts DNA and RNA. It includes the three types of RNA as well as the four bases of RNA. 

Viewers explore the structures of RNA and DNA and then learn how DNA replicates itself. The narrator explains the central dogma, showing how DNA is eventually translated into proteins, before briefly discussing genetic engineering. 

Don't leave genetics to the imagination! Demonstrate to your class the folding of RNA using a video animation. The animation shows the structure of RNA and how it folds on itself to create protein-like structures.

Messenger RNA, transfer RNA, and ribozymes ... the many faces of RNA. The structure of RNA makes it much more versatile than the very similar DNA. Learners view a slideshow presentation to learn all about the different forms and...

For years, scientists believed tRNA was junk left over from larger RNA. Three scientists used different approaches to prove tRNA actually exists as the connection between DNA and protein. Learn about their experiments, their lives, and...

A classic experiment that stumped scientists for years grabs the attention of young scholars. A slideshow presentation explains the experimental discovery of RNA interface. The lesson goes on to explain in detail the function of RNA...

Explore the history of DNA through Griffith, Avery, and Watson and Crick. The narrator of a science video briefly covers how DNA is organized in prokaryotic and eukaryotic organisms.
