Protein Synthesis (Updated)
 
08:47
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 details for contents and resources. 👇Video handouts and resources on http://www.amoebasisters.com/handouts. This video replaces our old protein synthesis video: https://youtu.be/h5mJbP23Buo Table of Contents: 0:46 Why are proteins important? 1:48 Introduction to RNA 2:22 Steps of Protein Synthesis 2:43 Transcription 3:54 Translation 6:08 Introduction to mRNA Codon Chart 7:51 Quick Summary Image Vocabulary in this video includes DNA, mRNA, rRNA, and tRNA. This video mentions that proteins can be made of 1 or more polypeptide chains and that proteins typically experience folding and other modifications (to be functional proteins.) Codons and the amino acids they code for is represented by standard charts can be found in the public domain. While the rectangle chart is the common format, there may be other ways to represent the information. P.S. If learning about mutations, check out this cool codon chart that includes mutations(!!) in the public domain: https://commons.wikimedia.org/wiki/File:Notable_mutations.svg Our videos are designed to introduce basic concepts and hopefully to inspire students to stay curious about the content. We simply cannot include all of the exceptions and minute details in a video under 10 minutes, and this is why we so frequently remind people of this in our videos. We want students to go beyond our videos to explore the depth of the material. P.S. On our website, we emphasize that our videos contain science comics- not scientific illustrations. In real life, amoebas don't look like our characters. Our illustrated cell cartoons are definitely not to scale. Nitrogen and carbon don't tap dance. DNA is right-handed (but there are exceptions- worth a google) and doesn't have eyes...a face...or a top hat...

Paul Andersen takes you on a tour of the cell. He starts by explaining the difference between prokaryotic and eukaryotic cells. He also explains why cells are small but not infinitely small. He also explains how the organelles work together in a similar fashion. Do you speak another language?
