3D Molecular Designs. Interact with and model the central dogma using this powerful simulation. Kit comes with durable color-coded foam nucleotides, tRNAs, placemats, and more, which allow students to model DNA replication, transcription of DNA into RNA, and translation of RNA into proteins. Addresses challenging concepts such as DNA strand directionality, anti-parallel structure, leadinglagging strands, and implications of encoded proteins due to changes in the DNA code. Demonstrates the structural differences between RNADNA and model the flow of genetic information from DNA to RNA to proteins. Teacher Notes (an activity guide) can enhance student understanding of the central dogma, and student handouts can supplement or reinforce concepts presented in the classroom; both are available online in PDF.
