This kit introduces genetic similarity and variation by evolutionary processes. Students can examine the evolution of the globin gene family with 3 dynamic activities.
In the first activity, students use magnetic nucleotide bases to model DNA and RNA structure. They generate a mutation in the sequence and investigate subsequent changes in the amino acid sequence. In the second activity, students focus on gene duplication by making cladograms. In the final activity, students model biotechnology techniques including restriction enzyme digestion, polymerase chain reaction, and gel electrophoresis to diagnose an individual with sickle cell anemia.
This 1-Station Kit equips up to 4 students and includes free 1-year access to digital resources that support 3-dimensional instruction.
