AdvancedFor experienced high school and college classes; requires some technical skill.
Students use safe saline mouthwash or hair and Chelex® extraction to obtain a sample of their own DNA. Then they use polymerase chain reaction (PCR) to amplify a 300-nucleotide Alu insertion into an intron of the H-cadherin gene. Gel electrophoresis separates the 2 alleles, and each student determines his/her own genotype. The experiment provides an introduction to human population genetics as participants learn to score genotypes and calculate genotype and allele frequencies.
Kit contains instructions, a CD-ROM, and materials for 25 students to perform DNA extraction, amplification, and electrophoresis (staining with CarolinaBLU®). Note: Kit includes a voucher to request perishable materials later at your convenience. Contact us or return the voucher to request delivery of perishable materials.
