DNA and RNA - Part 2

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...

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...

Try this quick, five question comprehension check over DNA, RNA, and protein. Each question has a hint available, as well as a self-checking feature.

Has your class finished its unit on genetics? Use this resource to provide a quick, encompassing review. Mr. Anderson discusses DNA, RNA, nucleotides, mitosis, meiosis, diploids, haploids, gametes, gene expression, etc. Create a...

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. 

In this online mini-course learners distinguish between the structure, functions, and processes involved with DNA and RNA.
