In This Assignment, Students Will Be Creating A Presentation

In this assignment students will be creating a presentation on innovations in biology and technology

In this assignment students will be creating a presentation on innovations in biology and technology. Students will submit a video link of a narrated PowerPoint or Slides presentation, along with a Word document of their narration (speaker’s notes), which will be reviewed for similarity by Turnitin. The presentation should cover how services like 23andMe and Ancestry collect and generate genomic data, including how this data is obtained and what it includes. It should start with a basic description of DNA and how genes control traits (the Central Dogma). The presentation should discuss the advantages and disadvantages of easy, rapid, and affordable access to genomic data, examine social implications such as benefits and risks, and consider the issue of Genome Privacy. Additionally, include a personal perspective—either your own or someone you know—on the decision to analyze one's genome, feelings about the results, or reasons for not pursuing such testing. This assignment addresses course outcomes related to the scientific method, differentiating scientific and pseudoscientific explanations, evaluating evidence, and applying biological principles and technologies to form questions, hypotheses, and draw conclusions.

Paper For Above instruction

Advancements in genomic technology have revolutionized the way individuals perceive their biological makeup and health risks. Personal genomics services, such as 23andMe and Ancestry, have made it accessible for the general public to explore their DNA, providing insights into traits, health predispositions, and ancestral origins. These services rely on sophisticated methods to analyze genetic material and generate comprehensive reports, raising important scientific, ethical, and social questions.

DNA, or deoxyribonucleic acid, forms the fundamental blueprint of biological information in living organisms. It is composed of nucleotide sequences that encode genetic information. Within each cell, DNA is organized into genes—specific segments that influence traits, from physical appearance to susceptibility to diseases. The Central Dogma describes how genetic information flows from DNA to RNA and then to proteins, which carry out various cellular functions. This process underpins how genes control traits and how genetic variations can influence individual differences.

Personal genomics services obtain genetic data primarily through saliva or blood samples. Once collected, the sample undergoes DNA extraction, purification, and amplification through polymerase chain reaction (PCR). The core technology involves genotyping, where specific known genetic variants (single nucleotide polymorphisms or SNPs) are analyzed using microarrays or sequencing technologies. These SNPs are locations in the genome where variation occurs among individuals. By comparing these variations with extensive databases, these services generate reports indicating health risks, traits, and ancestry. Some services, like Promethease, aggregate data from scientific literature to interpret SNPs in relation to known health conditions, giving users more detailed insights into potential disease predispositions (Kerklaan et al., 2017).

The advantages of easy and affordable access to genomic data are significant. It allows individuals to better understand their health risks, make informed lifestyle decisions, and engage in personalized medicine. It also fosters greater public awareness of genetics, promoting preventative health measures and early diagnosis. On the social level, democratizing genetic information can lead to empowered individuals and increased participation in scientific research, accelerating discoveries.

However, there are also notable disadvantages. The interpretation of genomic data can be complex and may lead to misunderstandings or anxiety if results are misinterpreted without professional guidance. There is also the risk of genetic discrimination by employers or insurance companies, despite legal protections such as GINA (Genetic Information Nondiscrimination Act) in the United States. Ethical concerns include the potential misuse of genetic information, privacy breaches, and the commercialization of genetic data, often without clear informed consent (Homer et al., 2017).

Social implications encompass both benefits and risks. Benefits include personalized healthcare, targeted treatments, and enhanced understanding of ancestry and identity. Conversely, risks involve privacy violations, stigmatization, and the potential for genetic data to be used in discriminatory ways. The issue of genome privacy is particularly pressing, as individuals may wish to restrict access to their genetic data to protect their privacy and prevent misuse. Unauthorized access or breaches could lead to discrimination or stigmatization, especially given the sensitivity of genetic information.

When considering whether to have one's genome analyzed, personal motivations vary. Some seek answers about inherited health conditions or ancestry, motivated by curiosity and the desire for proactive health management. Others may be hesitant due to privacy concerns, potential psychological impact, or ethical considerations. In my personal context, if I or someone I know had undergone genomic testing, I would have contemplated the emotional readiness to receive potentially distressing information and reassessed the importance of privacy protections. The feelings upon receiving results can range from excitement and empowerment to anxiety or regret, depending on the information revealed (Leroy et al., 2019).

In conclusion, personal genomics represents a remarkable convergence of biology and technology, offering transformative possibilities for health and understanding human history. Nonetheless, the ethical, privacy, and social challenges necessitate careful consideration. Informed decision-making, robust privacy safeguards, and education about the limitations and implications of genomic data are essential to maximize benefits and minimize harms. As technology advances, ongoing dialogue among scientists, policymakers, and the public is vital to ensure responsible use of genetic information.
