Yeast: a simple model system to study complex phenomena of aneuploidy

Area of Science:

• Genetics and Molecular Biology
• Cell Biology
• Disease Pathology

Background:

• Aneuploidy, an abnormal chromosome number, is implicated in various diseases and developmental disorders.
• Its role in human disease, particularly cancer, remains complex and debated due to experimental challenges.
• Recent advancements have highlighted the utility of yeast as a model organism.

Purpose of the Study:

• To review the contributions of yeast studies to the understanding of aneuploidy.
• To emphasize the experimental advantages of yeast for aneuploidy research.
