The Secret Of The Invisible Dna: A Genetics Exploration. In this lesson, students explore how DNA technology can be used to explore the relationship between genotype and phenotype using one of two exciting scenarios (medical diagnostics or alien genetics). Fluorescent dyes simulate DNA fragments, eliminating post-electrophoresis staining and saving you valuable classroom time.Kit includes: instructions, Ready-to-Load™ dye samples, agarose powder, practice gel loading solution, electrophoresis buffer, microtipped transfer pipets. All you need: electrophoresis apparatus, power supply, microwave or hot plate, and black light (BI130920 recommended).For: 10 Groups
