Examining A Functional Interaction Between Chromatin Remodeler Chd1 And Histone H1 In D. Melanogaster, Breanna Kim
Examining A Functional Interaction Between Chromatin Remodeler Chd1 And Histone H1 In D. Melanogaster, Breanna Kim
Scripps Senior Theses
Chromodomain-helicase-DNA-binding-protein-1 (CHD1) is a highly conserved ATP- dependent remodeling protein. It is localized to active genes and directs nucleosome spacing, while its loss has been linked to various human diseases, such as human prostate cancer. In Drosophila, CHD1 is important for fertility and wing development, and overexpression of CHD1 leads to severe wing vein defect phenotypes. The Linker Histone H1, which is known for maintaining heterochromatin and is associated with inactive genes, had been previously identified as a possible functional partner of CHD1, though the exact nature of their interaction is unclear. I undertook a genetic approach to examining the …
Crispr Genetic Editing: Paths For Christian Acceptance And Analysis Of In Vivo And In Vitro Efficiency, Mandeep Sandhu
Crispr Genetic Editing: Paths For Christian Acceptance And Analysis Of In Vivo And In Vitro Efficiency, Mandeep Sandhu
Scripps Senior Theses
With advancements in CRISPR-cas9 broadening the potential paths for clinical usage of genetic editing, conversations about genetic editing have grown to outside simply scientific communities and into mainstream conversations. This study focuses specifically on Christian discourse of genetic editing and locates four major tensions for many Christians when they think about genetic editing: beginning of life, Creator-human relationship, imago Dei, and stewardship. With these major concerns in mind, I identify epigenetics, somatic cell genetic editing, and in vivo genetic editing research as important research paths to pursue as they can potentially produce techniques that more Christian individuals would feel comfortable …
Developing A Gene Editing System To Study Haplodiploidy In The Jewel Wasp, Nasonia Vitripennis, Emily A. Muller
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 …
Family Matters: An Analysis Of Genetic Relatedness Of Tetraclita Rubescens (The Pink Volcano Barnacle) Over Several Spatial Scales At Monterey And Bodega Bay, California, Kelly N. Chang
Scripps Senior Theses
Inbreeding involves the mating of closely related individuals at a higher frequency than at random; this can decrease the average fitness of populations and individuals by reducing the presence of heterozygotes and augmenting the expression of deleterious genes. Since marine invertebrates exhibit widespread dispersal, their potential for inbreeding is often disregarded. The adult sessile state of barnacles creates the potential for inbreeding as a result of necessary copulation between neighboring individuals. Depending on the degree of mixing that occurs during dispersal, closely related individuals or siblings may settle in close proximity, generating the possibility of kin aggregation and consequent inbreeding. …
