Outline of Final Research Achievements

Gene expression is a stochastic process. Due to this, gene expression levels in single cells are inherently heterogeneous even among a genetically identical cell population. In this work, we challenged to develop a method to visualize single-molecule mRNA and protein productions in single eukaryotic cells. The results suggest that the protein translation process is a major source to regulate gene expression noise.
