Genetics
1. Why is yeast (Saccharomyces cerevisiae) used as a model organism in
projects?
In your answer include a brief description of yeast, why it is useful in a
laboratory environment, and why it is useful for genetic studies.
Yeasts are defined as eukaryotic unicellular fungi which have completely
different properties from the bacteria ones, of which are prokaryotic microorganisms.
It contains the same organelles of eukaryotic mature cell. Golgi apparatus, nucleus,
endoplasmic reticulum, cytoskeleton, vacuole and mitochondria are the most vital
ones. The primary way of yeast reproduction is occasionally by budding or fission. Its
natural habitat is soil, plants, animals, insects, plant tissues and water. Yeast is always
used in the lab because of the similarity of its cells to the human cells but portray fast
growth. According to (Karathia, Vilaprinyo, Sorribas & Alves, 2011), just like the
human cells have typical eukaryotic structure, yeast also has it including
mitochondria, cytoplasm and nucleus.
