Description: You can turn the nucleotide monophosphates in the basic DNA Starter Kit© into nucleotide triphosphates with the pieces in this expansion pack.
The extra phosphates allow your students to model the action of the DNA polymerase as it cleaves the triphosphate and joins the nucleotide
monophosphate to the growing DNA strand in replication. Triphosphates can also be used in transcription and to model ATP.
Each Triphosphate Expansion Pack includes 48 phosphate pieces and 48 connectors.
