These atomic model kits are informative and colorful. They can be used to assemble various configurations of base pairs, such as Watson Crick base pairs, restriction enzyme palindromes or small segments of DNA double strands. Concepts, such as base pairing, phophodiester bonds, opposite polarity of the sugar phosphodiester backbone, become real as students build these structures. The ten base model provides a small double stranded DNA structure which can be used to help students understand the primary, secondary and other structural elements of DNA, such as the minor and major grooves. As part of a cooperative effort, students can extend beyond the DNA structural elements and focus on concepts that include replication, transcription and translation. Ten DNA Base Pairs, A/T & G/C.
