Analyzing the origin of adaptive mutations in Saccharomyces cerevisiae Abstract Biological mutations play an integral role in the long-term survival of populations due to the potential benefit that the genetic variance provides. The main objective in this laboratory was to utilize the replica-plating technique to determine whether copper-tolerant mutants in Saccharomyces cervisiae arise spontaneously or if they are induced by their environment. This type of baker's yeast is ideal for mutation experiments due to the …showed first 75 words of 1556 total…

Other experiments that can be performed in the future for further comprehension of the origin of mutations include: exposing the yeast cells to different environments in order to observe if other similar pre-existing mutations exist and subjecting different types of cells to various environments in order to test the similarity between specimens. The experiment was effective in providing a good foundation for learning and observing the origin of adaptive mutants.
