Spatial Crowding And Confinement Effects On Bursty Gene Expression, Charles Wei-Shing Chin

Doctoral Dissertations

Synthetic biology and genetic engineering are valuable tools in the development of new, sustainable energy generation technologies. The characterization of stochastic gene expression is vital to the efficient application of genetic engineering techniques. Transcriptional bursting, in which periods of high expression are punctuated by periods of no expression, is extensively observed in gene expression. While various molecular mechanisms have been hypothesized to be responsible for transcriptional bursting, spatial considerations have largely been neglected. This work uses computational modeling to examine in detail the influence of spatial factors such as macromolecular crowding and confinement on gene expression.
