Journey Inside the Cell

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...

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...

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.

In this biology worksheet, students identify and label the diagram shown by stating what each part of the diagram represents on the line. Then they use the DNA strand as the original strand and complete the data table. Students also...

Through illustrations and data, viewers will understand either basic or advanced levels of DNA replication, RNA transcription, and protein translation. Click on images to move through this interactive program.

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...

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.
