Khan Academy: Molecular Genetics: 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:...

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...

Read about the structure of RNA, its components, and how they fit together. This source includes visual aids to help you and a list of the different kinds of RNA and their functions.

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. 

Explore how DNA, genes, and proteins are tied together to make life. Scholars learn about the central dogma, connecting DNA, which is inherited, to RNA and then to proteins, all which make the diversity of life today. 

Understand why the central dogma of molecular biology is amino acids with this video. [9:53]

Learn the basics of the Bronsted-Lowry definition of acids and bases in this video. [8:56]

The dengue virus looks like a ball with multiple layers. View an animation of each layer while hearing a description of its properties, from the outer symmetrical units to the lipid envelope, the capsid, and finally the RNA genome.

A lively presentation presents general facts and history of nucleic acids in a note-taking format. Every slide contains colorful photos or graphics to illuminate and engage. Biology aces learn about the function and structure of...

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...
