Using Dermatoglyphics from Down Syndrome and Class Populations to Study the Genetics of a complex tr
Dermatoglyphics is the study of epidermal ridges on the hands and feet. Ridge patterns and counts develop prenatally, are inherited, and show quantitative variation. This exercise introduces the preparation and interpretation of finger and palm prints for quantitative analysis. The techniques are simple, inexpensive, and can be adapted as an exercise on genetics for beginning or advanced students. Palm prints from individuals with Down Syndrome serve as a population sample to statistically test

These native proteins are often required for raising antibodies, and for studying enzymatic or regulatory function. Expression vectors are used to obtain large quantities of proteins. The cDNA encoding a protein is cloned into an expression vector. The fusion protein is over-expressed in E. coli,
