Lesson 3 — Protein Synthesis
Watch and Listen
Here are some animations and activities that you can complete to help you understand the process of mRNA translation. Complete the first two activities, and if time allows, watch the Youtube video and complete the RNA and Protein Synthesis Gizmo.
- The following animation is an excellent view of the translation process. As you watch the animation, note how the anticodon on the tRNA molecule and the codon on the mRNA are complementary to one another. Give attention to the slowly forming polypeptide
(protein) from the bonding amino acids. Do not worry about the extra details such as sites P and A; you do not need to know this for the Biology 30 course. Watch the process of the amino acids joining to become a protein molecule.
- You may prefer to watch the Biologix video Protein Synthesis: Translating the Code that describes the translation process. An effective animated review of transcription and translation is at the end of the video.
