Demo DNA Nucleotides^© Teacher Resources

Teacher Notes

You can use our large-scale, color-coded foam Demo DNA Nucleotides to introduce basic DNA concepts to your students before they explore the DNA Discovery Kit, DNA Starter Kit and/or Flow of Genetic Information Kit to discover the structure and function of DNA. It also works well for review.

You can cover a whole host of DNA topics:

• Complementary A-T and G-C base pairing
• Anti-parallel nature of double-stranded DNA
• Semiconservative nature of DNA replication
• Transcription (Use white stickers, available at office supply stores, on thymine to indicate uracil.)
• PCR (polymerase chain reaction)
• Sanger DNA sequencing method

As a wrap-up ask your students to compare the strengths and weaknesses of each of the models.

Please consider contacting us with any lessons and activities you develop that we could share with other teachers. Please also keep in touch – we enjoy hearing from you about how you use our kits and models in your classrooms!
