Developing A Gene Editing System To Study Haplodiploidy In The Jewel Wasp, Nasonia Vitripennis, Emily A. Muller
Scripps Senior Theses
Hymenopteran insects, which include all ants, bees and wasps, reproduce through a poorly understood form of reproduction known as haplodiploidy. A promising experimental system for understanding this developmental process is the jewel wasp, Nasonia vitripennis. A critical aspect of using Nasonia as a model is establishing an effective means for editing specific genes of interest so that their functions can be studied through genetic means. For my thesis research, I performed a pilot study of the gene editing method known as CRISPR in Nasonia. I targeted the single heterochromatin protein 1 (HP1) gene present in the Nasonia genome …

Investigating The Influence Of Chd1 On Gene Expression In Drosophila Melanogaster Using Position Effect Variegation, Phuongngan Thi Bui
Scripps Senior Theses
Position Effect Variegation (PEV) is the mosaic expression of a gene that has been moved out of its optimal environment and into a different area on the chromosome. Changing a gene’s environment may have profound effects on its eligibility for proper expression, which is a complicated process regulated by many factors. The PEV phenomenon is used as an assay to study gene expression as regulated by chromatin structure. In this study, the Drosophila melanogaster white gene was used as a reporter to study the various effects of CHD1, a chromatin regulating factor, on PEV gene expression. Inspired by preliminary data …
