Help students clearly visualize the steps of protein synthesis and save time creating lesson demonstrations. First, draw a picture of a cell on the board, complete with nucleus, ribosomes, ribosomal subunits and a membrane. Then, using the magnetic pieces and Velcro® in this kit, you can manipulate these large magnetized models in and around your drawing to clearly illustrate the different phases of the synthesis process.The models include a DNA double helix that separates, a complementary strand of mRNA, and four tRNA models, all of which fit together like a puzzle. Four amino acid models and three peptide bonds are also included. Teacher Patricia Herzberg developed these large magnetized models for easy viewing from all areas of the classroom. Partial assembly required. Includes a teacher’s guide with instructions. Grades 9–12.
