The Ethical Implications Of Bioengineering Advancements, Mainstream Media Coverage Of Those Developments, And The Future Of Motherhood, Aliff Abad, Katherine Gregory Dec 2019

The Ethical Implications Of Bioengineering Advancements, Mainstream Media Coverage Of Those Developments, And The Future Of Motherhood, Aliff Abad, Katherine Gregory

How do the media interpret reproductive interventions that involve genetic testing? When a scientist performed the first known genetic editing on twins, Lulu and Nana, he ignored ethical considerations of CRISPR use. This project provides a content analysis based on a review of popular science and newspaper articles. Our interpretation of these articles suggest that there is a lack of critical understanding of this unethical procedure and a similar attitude towards future genetic developments. While the public is curious about the repercussions of genetic editing, not enough focus is applied to the ethics of conducting such a procedure.


Exploring Secondary Structure In Bacteriophage Programmed Frameshift Elements, Samuel Okabayashi, Sean Mcclory Nov 2019

Exploring Secondary Structure In Bacteriophage Programmed Frameshift Elements, Samuel Okabayashi, Sean Mcclory

HON499 projects

Bacteriophages are viruses that infect bacteria and reproduce using host bacterial components. Part of the bacteriophage reproduction is assembly of the tail complex, which requires two assembly chaperone (TAC) proteins. In many phages the TAC’s are produced from a single gene through a non-canonical process called programmed translational frameshifting (PTF). The SEA-PHAGES program has produced hundreds of TAC genes that are accessible through phagesdb, a database of sequenced and annotated phage genomes. The sequences for the TAC gene were gathered from phagesdb and analyzed using ClustalOmega; a multiple sequence alignment (MSA) tool which revealed several positions where total conservation was …


Determining The Functions Of Novel Genes Required For Photosynthesis, Gillian Gomer, Moshe Kafri, Martin Jonikas Jul 2019

Determining The Functions Of Novel Genes Required For Photosynthesis, Gillian Gomer, Moshe Kafri, Martin Jonikas

Gillian Gomer

As land available for agriculture remains limited, it is becoming more necessary to explore methods to improve the efficiency of crop production in order to support Earth’s growing populations. Newly characterized photosynthetic genes could improve our understanding of the way organisms convert light energy into fuel, allowing improvements in plant growth and environmental resistance. Using an insertion mutant library of the unicellular algae, Chlamydomonas reindhartii, that covers 83% of its genome, we are identifying and characterizing the hundreds of genes associated with photosynthesis. Chlamydomonas can be grown with or without a light source, which allows us to identify mutants displaying …


Genetic Diversity Of Local Canines Assessed By Derived Cleaved Amplified Polymorphic Sequences, Nicole Benmoshe, Jeremy Seto May 2019

Genetic Diversity Of Local Canines Assessed By Derived Cleaved Amplified Polymorphic Sequences, Nicole Benmoshe, Jeremy Seto

Publications and Research

Breeding of the dog, Canis Iupus familiaris, over centuries has given rise to the selection of certain traits including size, shape, coat length, color and many behavioral traits. Inbreeding within dog breeds has resulted in the increase of genetic diseases, many of which are similar to human diseases making the dog an exemplary model organism to study. Using dCAPS (Derived Cleaved Amplified Polymorphic Sequences) we can identify SNPs (Single Nucleotide Polymorphisms) in the dog genome using buccal samples collected from four local dogs of different breeds, both large and small. After performing DNA extractions, PCR (Polymerase Chain Reaction), restriction enzyme …


Co-Occurrence Of Manganese Oxidase Genes Indicates Lateral Transfer Between Classes Of Proteobacteria, Jacob Olichney Apr 2019

Co-Occurrence Of Manganese Oxidase Genes Indicates Lateral Transfer Between Classes Of Proteobacteria, Jacob Olichney

Student Scholar Showcase

Pseudomonas putida GB-1 is a model organism for the study of manganese oxidation in bacteria, however, the frequency of co-localization of multiple known and suspected manganese oxidizing proteins, as well as their occurrence between species, is unknown. Eight different genes isolated from known manganese oxidizing bacteria (MnxG, MopA, McoA, PputGB1_2552, PputGB1_2553, MoxA, MofA, and Bacillus MnxG) were tested individually using BioPython and BLAST (Basic Local Alignment Search Tool) on multiple genomic databases. BLAST searches had an expect value cutoff of 1e-50, limiting gene homologs to those with high sequence similarity. The abundance of homologous genes across classes of proteobacteria point …


Meta-Analysis Of Characteristics In Upper Missouri River Fishes: Prediction Of Invasiveness, Steph Purcell Mar 2019

Meta-Analysis Of Characteristics In Upper Missouri River Fishes: Prediction Of Invasiveness, Steph Purcell

UNO Student Research and Creative Activity Fair

Invasive species are often considered a global threat due to their association with biodiversity loss and novel diseases. The Missouri-Mississippi River Watershed, including the Missouri River Basin, is particularly vulnerable to invasive species because of low species diversity following historic glaciation events. Management of invasive species is imperative in this watershed but continues to be challenging in that there are over 100 invasive species currently present in this region. The goal of this project is to identify characteristics associated with successful invasions that may assist in developing management strategies to reduce the negative outcomes caused by the establishment of invasive …


Gene Co-Expression Networks Analysis Reveal Novel Molecular Endotypes In Alpha-1 Antitrypsin Deficiency, Jen-Hwa Chu, Wenlan Zang Jan 2019

Gene Co-Expression Networks Analysis Reveal Novel Molecular Endotypes In Alpha-1 Antitrypsin Deficiency, Jen-Hwa Chu, Wenlan Zang

Yale Day of Data

Rationale:Alpha-1 antitrypsin deficiency (AATD) is a genetic condition that predisposes to early onset pulmonary emphysema and airways obstruction. The exact mechanism through which AATD leads to lung disease is incompletely understood.

Objectives: To investigate the effect of AAT genotype and augmentation therapy on bronchoalveolar lavage (BAL) and peripheral blood mononuclear cells (PBMC) transcriptome, while examining the link between gene expression profiles, and clinical features of AATD.

Methods: We performed RNA-Seq on RNA extracted from BAL and PBMC on samples obtained from 89 AATD patients enrolled in the Genomic Research in Alpha-1 Antitrypsin Deficiency and Sarcoidosis (GRADS) study. Differential …
