Explain Why Budding Yeast (Saccharomyces Cerevisiae)is a Particularly Useful Tool

Question

Examlex · Accepted Answer

The Answer is Budding yeast can easily be switched between either a diploid or haploid growth phase.Therefore mutations that would be lethal as haploids can be rescued (complemented)as diploids,and conversely,mutant genotypes can be assembled in the diploid phase and tested for lethality or other phenotypes in the haploid phase.Furthermore,the highly efficient homologous recombination system in yeast is an effective means of targeted gene replacement or gene deletion,even at a genomic scale.Indeed,collections of yeast strains each bearing a mutation in a gene of interest are commercially available.Yeast also has other advantages such as fast growth and compact size,which make it well-suited to automated high density screening.The major drawback of yeast is that it is unicellular.Thus,many genes and pathways specific to multicellularity cannot be studied in yeast.
