DNA, RNA - Protein Synthesis Kit

Complete for 24 students working in pairs.
 
This kit demystifies the DNA/RNA connection in protein synthesis. Using individualized student worksheets and plastic, color-coded components, students first build a DNA molecule, replicate it, and use half of the "ladder" to build mRNA (messenger RNA). Nucleotides of RNA are first produced following these step-by-step directions, making the chemistry easily understood. Transcription in the nucleus and the movement of the mRNA molecule are simulated by placing it on a model ribosome. At this time, translation is simulated by matching the mRNA and its codons to the tRNA (transfer RNA) and its anticodons. The amino acids bond to form a protein molecule. Students experience how the information stored in DNA is expressed as a finished protein.
Students conclude by disconnecting the protein chain from the tRNA and the tRNAs from the mRNA, showing their availability to continue the process.
