Khan Academy: Molecular Structure of 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:...

Learn the basics of the molecular structure of RNA in this video. Video discusses structure as well as compares the structure of RNA vs. DNA. [11:29]

Learn the molecular structure of DNA including the nucleotide, nitrogenous base, and phosphate. [13:00]

Look at the molecular structure of DNA. Investigate nucleotides, nitrogenous bases, and phosphates. [13:00]

Learn the molecular structure of RNA. [11:29]

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...

A video giving an overview of the molecular structure of glucose. Explore the monosaccharide structure with the linear and ring forms. [9:18]

A video reviewing over the molecular structure of fructose. Video compares fructose with glucose and learn how sucrose is made from both. [9:38]

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.

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.
