Analyzing the origin of adaptive mutations in Saccharomyces cerevisiae

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 …

…aptive mutants arise in populations. 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.
