You’ve probably heard of mRNA, thanks to the COVID-19 vaccine. But what is mRNA exactly? In this episode of Crash Course Biology, we learn about the role of messenger RNA in living things and how it decodes our DNA instruction manual...

In this video Paul Andersen explains the difference between diploid and haploid cells. He starts with a brief description of the central dogma and how genes code for proteins. He then uses the phenotype of red hair to explain that...

Explore the steps of transcription and translation in protein synthesis! This video explains several reasons why proteins are so important before explaining the roles of mRNA, rRNA, and tRNA in the steps of protein synthesis! Expand...

In this video Paul Andersen explains the importance of DNA is organisms. DNA contains the blueprint for each organisms. The DNA codes for the mRNA which creates proteins. The DNA also is the unit of inheritance which is...

As you get older, your eyes worsen and become susceptible to a disease called age-related macular degeneration -- the leading cause of blindness, with no cure in sight. Sharing the science of how your vision works, researcher Joshua...

Paul Andersen describes three main characteristics of life that are conserved in all organisms on the planet. The universal genetic code, the central dogma of biology, and shared metabolic pathways give us details of the original...

Mr. Andersen explains the Central Dogma of biology. He shows how DNA is transcribed to form mRNA and how mRNA is translated into a protein.

Paul Andersen previews the information in the genetics unit. He defines the central dogma of biology and explains how DNA creates an RNA transcript that is used to translate proteins. He differentiates between mitosis and meiosis. He...

Paul Andersen explains the central dogma of biology. He explains how genes in the DNA are converted to mRNA through the process of transcription. He then explains how ribosomes use this message to convert the mRNA to a functioning...

Paul Andersen continues his description of DNA and RNA. He begins with the structure of DNA and RNA and moves into the process of DNA Replication. He also describes the central dogma of biology explaining how DNA is transcribed to mRNA...

A video explaining and illustrating all steps of transcription.

This video will explain and illustrate all steps of protein synthesis, starting with processing the RNA, followed by making a protein at the ribosomes (translation).

Peptidyl Transferase/Ribosome Physiology, Biochemistry, and Mechanism

Transcription: Biosynthesis of RNA

This video explores the Central Dogma of Molecular Biology (Transcription & Translation) at an introductory or general biology level.
