Counting on DNA Did you know that the complexity of human chromosomes (the "stuff" from which we are made) reduces to four very simple repeating units? Amazingly, these same four repeating units define the diversity of all life, both plant and animal, on earth. Participants in this workshop will gain insight into the nature of these DNA building blocks and at the same time learn how scientists and mathematicians isolate, study, and formulate mathematical models to relate the DNA from different organisms to each other. This workshop will be conducted in the Penn State biology laboratory. Students will have an opportunity for hands-on experience, including microscopic examination and photography of chromosomes, loading agarose gels, and simple mapping of DNA sequences.
