Mrs. Ashkenazy’s Biotechnology class have submitted two proposals to the prestigious Urban Barcode Project Competition. In this competition students from all over New York will isolate a unique DNA barcode of different species. Just as a unique pattern of bars in a universal product code (UPC) identifies each item for sale in a store, a DNA barcode is a DNA sequence that uniquely identifies each species of living thing.
Tommasina Cardone, Julia Nelson, Giuseppa Bruno and Margaret Minogue have submitted a proposal to “barcode” the Illex illecebrosus (a species of squid), and Julia Perez, Elizabeth Carmody and Maya Volchock have submitted a proposal to “barcode” Limnodynastes tasmaniensis (a grass frog). In this picture, they have been examining a dogfish shark - as Anna Acevedo and Lenette Aaron would like to “barcode” Squalus acanthias (a dogfish shark).
