Protein synthesis section of any good biology textbook.

The newly formed polypeptide chain undergoes several modifications before becoming a fully functioning protein. Proteins have a . Some will be used in the , while others will remain in the or be transported out of the . Many copies of a protein can be made from one mRNA molecule. This is because several can translate the same mRNA molecule at the same time. These clusters of ribosomes that translate a single mRNA sequence are called polyribosomes or polysomes.

Simonds Drawing Video:Summary of Protein Synthesis

Protein from animal sources, such as meat and milk, is called complete, because it contains all nine of the essential amino acids. Most vegetable protein is considered incomplete because it lacks one or more of the essential amino acids. This can be a concern for someone who doesn't eat meat or milk products. But people who eat a vegetarian diet can still get all their essential amino acids by eating a wide variety of protein-rich vegetable foods.

an analogy that I have written to help students to understand the basic process for protein synthesis. Students seem to really like it and understand from the analogy.


Transcript of Protein Synthesis Project

Translation occurs in the . After leaving the , mRNA must undergo several modifications before being translated. Sections of the mRNA that do not code for amino acids, called introns, are removed. A poly-A tail, consisting of several adenine bases, is added to one end of the mRNA, while a guanosine triphosphate cap is added to the other end. These modifications remove unneeded sections and protect the ends of the mRNA molecule. Once all modifications are complete, mRNA is ready for translation.

Protein synthesis is accomplished through a process called translation. After is transcribed into a messenger (mRNA) molecule during , the mRNA must be translated to produce a . In translation, mRNA along with (tRNA) and work together to produce proteins.

Protein Synthesis - how protein is made, simplified

1. Along with your unit test on the DNA unit, include the "practical" test supplement, requiring students to decipher a short DNA message during a test. Provide the (including tRNA Dictinary), the special answer sheet, and a unique word for each student (on little slips of paper, which you can prepare from the sample sentences provided, or use the 33 3-letter provided (along with a for you to use in grading the test.).. Insist that each step be shown and the molecules involved be labeled (DNA, mRNA, tRNA, "protein" (as the "meaningful amino acid sequence"). Include completeness and accuracy in showing these steps and labels in your grading.

1. Original Source: Larry Flammer, idea developed in 1963 and used in Biology classes ever since, as the finale to a series of Do-It-Yourself DNA Kits (1. DNA Structure & Sub Structure, 2. DNA Replication, and 3. Protein Synthesis, all involving manipulation of cutouts, and resulting in the spelling out of a little 3-letter word (meaningful amino acid sequence).
