The tRNA molecules bind to the mRNA strand if their 3 letter codes match. The tRNA molecules arrive towing amino acids, the building blocks of proteins. The amino acids join to form a protein chain and in the last step, the protein folds into its final shape. <p>Here you see that the protein folds up into a short helix. Next, four of these folded proteins can create a channel protein in the cell membrane (yellow circles). These four protein chains have hydrophobic amino acids (yellow) around the outside edges. The hydrophobic amino acids orient the proteins towards the lipid molecules in the membrane. The pore or channel in the center (darkest area) allows ions to enter the cell. </p><p>Find out more on the <a href="http://www.sciencebuilders.com/legoanimations.html" target="_blank">Science Builders</a> website.</p><p>This activity is a facilitated school program for high school students at the MIT Museum. </p> 243 tag:techtv.mit.edu,:Array/219349960 2008-01-29 17:48:21 -0500 MIT Museum <p>Transcription of DNA.

However, he worried that he may have been sold the wrong variety. Since certification of the variety based upon phenotypic characteristic is possible only after several years, how can the farmer identify olive cultivars before waiting that long? 1796
