Budding yeast, Saccharomyces cerevisiae, is a powerful model for studying gene function through mutational analysis. Genetic studies in yeast reveal fundamental principles of histone and nucleosome function applicable to all eukaryotes.

Area of Science:

  • Genetics
  • Molecular Biology
  • Cell Biology

Background:

  • Mutational analysis is crucial for understanding gene function.
  • The budding yeast Saccharomyces cerevisiae is a well-established model organism for genetic studies.
  • Histone and nucleosome structure is conserved across eukaryotes.

Purpose of the Study:

  • To highlight the utility of Saccharomyces cerevisiae for dissecting histone gene function.
  • To describe recent advancements in manipulating yeast histone genes.
  • To emphasize the broad applicability of yeast-derived genetic principles to eukaryotic chromatin.

Main Methods:

  • Utilizing Saccharomyces cerevisiae as a model system.
  • Employing genetic strategies for in vitro manipulation of histone genes.
