SYNTHETIC BIOLOGY

 
 
 
Synthetic biology refers to the science of using genetic sequencing, editing, and modification to create unnatural organisms or organic molecules that can function in living systems. Synthetic biology enables scientists to design and synthesise new sequences of DNA from scratch
Synthetic biology is an exciting and rapidly evolving field that blurs the lines between biology and engineering. It\'s the art of designing and building new biological systems and functions from scratch, utilizing the building blocks of nature like DNA, proteins, and cells. Imagine it as playing with biological lego blocks, assembling them in novel ways to create something entirely new
 
Synthetic biology represents an emerging sector within the scientific domain that amalgamates engineering and computer programming with biological sciences. The rapid evolution of technology is enabling the integration of human bodies with this technology for optimal health and efficacy. In the forthcoming era, rather than relying on medications, the immune system could be programmed to autonomously combat invading pathogens. The realm of synthetic biology encompasses a broad spectrum within science, encompassing tasks from modifying antibodies and regenerating lost limbs to cultivating lab-grown meat and editing DNA to eliminate existing conditions (such as CRISPR, unveiled in 2012).
Its societal impact is vast and indefinite, carrying numerous social, political, economic, environmental, and technological implications, some of which could be irreversible. Stakeholders in synthetic biology encompass a wide array, including healthcare professionals, scientists, agriculturalists, government entities, pharmaceutical industries, and every individual influenced by these transformations.
Predicting a future untouched by gene editing seems challenging, as it is likely to impact agriculture, medicine, and even intersect with the effects of climate change
 
Applications of Synthetic biology
  • Emerging trends in synthetic biology encompass various advancements, such as the adoption of mRNA vaccines, SNP profiling, organoids, assembloids, molecular innovations, and genetic modifications.
  • For instance, the first FDA-approved mRNA vaccine emerged in 2020 with the COVID-19 vaccine, signaling the potential for mRNA vaccines to streamline testing, development, and cost, as noted by the Association of American Medical Colleges.
  • SNP Profiling, originating from studies in 2010, involves altering a fetus\' DNA within the mother\'s body, offering possibilities like designing eye color or averting developmental disorders at parental discretion.
  • Organoid-based xenotransplantation, utilizing host stem cells to cultivate organs in labs, addresses transplant rejection concerns due to identical DNA sequences.
  • Its potential significance is heightened amid organ donor shortages. Pioneering developments, including brain organoid creation in 2008, have propelled research into disorders like Autism and Schizophrenia.
  • Assembloids, three-dimensional tissue models developed in 2017, akin to organoids but encompassing diverse cell types, play a pivotal role in disease research and human development by allowing in-depth observation of cell growth and evolution.
  • Molecular innovation opportunities entail molecule discovery, DNA content and storage alteration, and engineered animals for human welfare.
  • Beginning in the 1930s, molecular biology has evolved to target diseases. Discovering novel molecules is critical for drug development and immune system enhancement.
  • DNA alteration, initiated in 1973, led to insights into restriction enzymes and DNA ligases, crucial for forming new genetic sequences.
  • Envisioning human DNA holding vast data capacities suggests unlimited potential for human data storage in the future.
  • Engineered animals represent a synthetic biology application extending beyond humans, benefitting the environment by reducing carbon emissions, thereby aiding the fight against climate change
What are the Potential Negative Impacts of Synthetic Biology?
 

Synthetic biology, like any emerging technology, brings about potential negative impacts that warrant consideration. Some of these include:

Ethical Concerns: Altering the fundamental characteristics of living organisms and manipulating genetic codes raises ethical dilemmas. Questions about playing \"nature\'s role\" and potential unintended consequences of modifying living organisms are pertinent.

Biosecurity Risks: Engineered organisms or novel genetic sequences could pose biosecurity risks if they are accidentally released into the environment or intentionally misused for harmful purposes, potentially leading to ecological disruptions or even bioterrorism.

Unintended Consequences: Modifications in organisms might have unforeseen consequences on ecosystems, biodiversity, and interactions within ecological systems, affecting natural balances and potentially causing ecological imbalances or unintended harm.

Social and Economic Disparities: Access to and control over synthetic biology innovations could exacerbate socio-economic disparities. Unequal access to advanced treatments, genetically modified crops, or bioengineered solutions could deepen existing divides.

Health Risks: While synthetic biology holds promise in healthcare, there are concerns about the long-term health impacts of genetically modified organisms (GMOs) on humans or unintended health consequences due to gene editing.

Intellectual Property Rights (IPR): IPR issues could arise in synthetic biology, leading to monopolization or restricted access to technologies, hindering innovation and impeding the sharing of benefits or advancements.

Environmental Impact: The release of genetically modified organisms into the environment could have irreversible effects on ecosystems, including unintended cross-breeding with natural species, leading to ecological disruptions or loss of biodiversity.

Regulatory Challenges: Governing and regulating the rapidly evolving field of synthetic biology pose challenges. Establishing appropriate regulations and oversight to ensure safety and ethical standards can be complex

 
What are Governance, Policy And Regulatory Aspects Relevant To Synthetic Biology?

The governance, policy, and regulatory aspects relevant to synthetic biology are complex and evolving, as the field itself is rapidly pushing boundaries. Here\'s a breakdown of the key areas:

Governance:

  • International Governance: Frameworks like the Convention on Biological Diversity (CBD) and the Cartagena Protocol on Biosafety provide overarching principles for managing potential risks of genetically modified organisms (GMOs), which might encompass some synthetic biology applications.
  • National Governance: Individual countries, like India, are developing their own governance structures, with initiatives like the National Biosecurity Action Plan (NBAP) aiming to address biosecurity risks associated with emerging technologies like synthetic biology.
  • Stakeholder Engagement: Public engagement, involving scientists, industry, ethicists, and the public, is crucial for building trust and informing responsible governance practices.

Policy:

  • Risk Assessment and Management: Policies need to establish robust risk assessment frameworks to identify and mitigate potential ecological, human health, and social risks associated with synthetic biology research and applications.
  • Intellectual Property Rights (IPR): Clear IPR policies are needed to incentivize innovation while ensuring equitable access to and benefit-sharing from synthetic biology advancements.
  • Funding and Incentives: Government and private funding mechanisms can encourage responsible research and development in synthetic biology, ensuring alignment with societal needs and ethical considerations.

Regulation:

  • Regulations governing GMOs, biosecurity, and environmental impact assessments might apply to some aspects of synthetic biology, but gaps and uncertainties often exist.
  • Dedicated regulations addressing the unique features and risks of synthetic biology are yet to be widely implemented, but discussions and pilot initiatives are underway in various countries.
  • International and national regulatory frameworks need to work in concert to avoid inconsistencies and facilitate responsible global development of synthetic biology.
