Demo DNA Nucleotides

The sky is the limit to what you can teach using these new large-scale, colour-coded foam nucleotides. Begin by teaching the complementary A-T and C-G base pairs and the antiparallel nature of double-stranded DNA. Move on to the flow of genetic information as you teach the basic processes of semiconservative DNA replication and mRNA transcription. You can then stretch students by introducing PCR (polymerase chain reaction) and the Sanger DNA sequencing method -- and much more. 80 Large-Scale Nucleotides: 20 Red Adenosine 20 Yellow Thymine 20 Blue Cytosine 20 Green Guanine 80 Adhesive-Backed Round Magnets
