Protein Synthesis: Transcription and Translation (Updated)

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 Video has been dubbed using an artificial voice via https://aloud.area120.google.com to increase accessibility.

Table of Contents: 00:00 Intro 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 are represented by standard charts that 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 We cover the basics in biology concepts at the secondary level. If you are looking to discover more about biology and go into depth beyond these basics, our recommended reference is the FREE, peer reviewed, open source OpenStax biology textbook: https://openstax.org/details/books/biology -------------------------- Corrections: 1:19: By "few exceptions," we mean there are some exception TYPES of body cells. Like mature red blood cells. Quantity-wise though, there are a LOT of red blood cells; they make up the bulk of numerical cell count. --------------------------- Biology Video Playlist: https://www.youtube.com/playlist?list=PLwL0Myd7Dk1F0iQPGrjehze3eDpco1eVz The Amoeba Sisters videos demystify science with humor and relevance. The videos center on Pinky's certification and experience in teaching biology at the high school level.
