Lab-Aids: DNA/RNA Protein Synthesis Modeling Kit
Demystify the DNA/RNA connection in protein synthesis. This hands-on modeling approach makes the complex chemistry of DNA/RNA protein synthesis easily understood! The kit includes twelve packets of color-coded molecular model components.
Following step-by-step directions, students will:
- Build and replicate an eight-rung DNA molecule‚
- Use half the DNA ladder to build mRNA (messenger RNA)‚
- Simulate mRNA movement by placing the mRNA on a ribosome‚
- Simulate translation by matching the mRNA and its codons to the tRNA (transfer RNA) and its anti-codons‚
- Disconnect the protein chain so the process can continue
Scientific Concepts:
- Demystifies the DNA/RNA connection in protein synthesis
- Replication, transcription and translation is modeled
- Experience how information stored in DNA is expressed as a finished protein
