Synthetic Chromosomes, Transcriptomes, And Patents On BRCA G

Synthetic chromosomes, Transcriptomes, and Patents on BRCA genes

For your primary post, please respond to one of the following three topics with a post of at least 125 words that addresses each point given in the instructions. Also, please reply to at least one fellow student on any topic. Topic 1 [videos]: It’s parent was a computer file. Watch the short video about organisms with a synthetic chromosome that was created at the Craig Venter Institute (1) and the video about the “streamlined” version of that organism(2). Subsequently, answer the following: (a) How does the DNA in the synthetic organisms differ from DNA in naturally-occurring microorganisms? (b) What do you think we’ve learned from these experiments? (c) In your opinion, what are the inherent risks of this research to human health or to the environment, if any? Topic 2 [article]: Transcriptomes. The complete set of all DNA in a cell is called the genome. The complete set of all the mRNA in a cell is called the transcriptome. Read the following article about the transcriptome (1)*, then address the following: (a) What does the transcriptome tell us that we can’t get from the genome? (b) If we compare the transcriptome between cells that have completely different functions in the body, how do you think they would compare? (c) Explain how this concept relates to our lesson on gene expression from Chapter 7. Topic 3 [research]: Patent protection for BRCA genes. On the Internet, read one or more articles about how the Supreme Court of the United States (SCOTUS) ruled in the case of Association for Molecular Pathology versus Myriad Genetics. In your answer, you must give credit to your source(s). Your answer must address the following: (a) Describe some of the major reasons why the plaintiffs objected to Myriad’s patent on the breast cancer-related genes, BRCA1 and BRCA2. (b) Describe the SCOTUS ruling regarding naturally-occurring DNA sequences, as well as their ruling regarding DNA sequences that do not exist in Nature. Note: the rulings of lower courts are NOT of interest for our purposes. Please concentrate only on SCOTUS's ruling. The objective here is to emphasize the precedent-setting ruling of the highest court (SCOTUS), rather than to recount the litigation history. (c) What is your view on the issue of whether we should allow human genes to be patented? Be absolutely sure that you cite your sources, and list your references.

Paper For Above instruction

The advent of synthetic biology has revolutionized our understanding of genome manipulation, offering unprecedented insights into genetic functions and applications. The creation of synthetic chromosomes, as undertaken by the Craig Venter Institute, exemplifies this progress. Synthetic organisms differ significantly from naturally-occurring microorganisms primarily in their genetic content and construction. Synthetic organisms are designed with a minimal set of genes necessary for survival, often excluding redundant or non-essential genes, rendering their DNA more streamlined and tailored compared to natural genomes (Gibson et al., 2010). This deliberate minimalism not only facilitates understanding gene functions but also harnesses potential industrial and medical applications. From these experiments, scientists have learned how minimal genomes sustain life, enabling better control over organism behavior and metabolic pathways. Such knowledge fuels advancements in bioengineering but also raises concerns about potential biosafety risks. The primary risks involve the accidental release of synthetic organisms into ecosystems, potentially disrupting existing microbial communities or transferring genetic material to native species (Church et al., 2014). Moreover, these organisms' ability to thrive outside controlled environments could pose health risks if pathogenic traits emerge or are unintentionally propagated. Conversely, regarding transcriptomes—the entire set of mRNA molecules in a cell—these reveal active gene expression that is not evident from the genome alone (Conesa et al., 2016). This set indicates which genes are actively transcribed under specific conditions, providing a dynamic picture of cellular activity. For instance, two cells with identical genomes can have vastly different transcriptomes, explaining their divergent functions in tissues. This concept closely relates to gene expression studies, emphasizing how gene activity, rather than mere presence, determines cell function (Liao et al., 2014). Lastly, in the legal realm, the Supreme Court's decision in Association for Molecular Pathology v. Myriad Genetics marked a pivotal moment. Plaintiffs contended that Myriad's patent on BRCA1 and BRCA2 genes limited research and access, claiming that naturally occurring DNA sequences cannot be patented because they are products of nature (Myriad Genetics, Inc., 2013). The Court ruled that naturally occurring DNA sequences, isolated but identical to those in the body, are not patentable because they are products of nature. However, synthetic DNA sequences or cDNA, which do not naturally occur, can be patented (Supreme Court, 2013). This ruling creates a legal precedent limiting gene patents and encourages research without monopolistic restrictions. Personally, I believe that patenting human genes inhibits scientific progress and equitable healthcare by restricting research and access to genetic testing. Allowing patents only on synthetic sequences or inventions derived from natural genes balances innovation incentives with broader public benefit (Kumar & Stepanova, 2015). In conclusion, advances in synthetic biology and genomics are reshaping science, but ethical and legal considerations remain critical in guiding responsible innovation.
