The Department of Biotechnology under Ministry of Science and Technology has recently released a draft foresight paper on synthetic biology. Synthetic biology has numerous energy, agriculture, and biofuel applications. As a result, there is always the perceived risk of components leaking into the open environment. As a result, the document emphasises the importance of a national policy that can solidify India's position on the issue. In this article, we will discuss in detail regarding Synthetic Biology and its implications which will be helpful for UPSC exam preparation.

Synthetic Biology – Background

• The research into 'synthetic biology,' i.e., developing organisms and products that are completely new to the world began decades ago.
• Barbara Hobomin coined the term 'synthetic biology' in 1980 to describe bacteria that had been genetically engineered using recombinant DNA technology.
• The Craig Venter Institute in the United States created the first artificial life form, dubbed 'Synthia,' in 2010.
• Synthetic biology has captured the imagination of scientists in less than nine years, and the industry's market of $11 billion in 2016 is expected to grow to $100 billion by 2025.

What is Synthetic Biology?

• The science of using genetic sequencing, editing, and modification to create unnatural organisms or organic molecules that can function in living systems is known as synthetic biology.
• Synthetic biology allows scientists to create new DNA sequences from scratch.
• It is a branch of science that involves engineering organisms to have new abilities in order to redesign them for useful purposes.
• Researchers and companies all over the world are harnessing nature's power to solve problems in medicine, manufacturing, and agriculture.
• The term was used to describe the creation of unnatural organic molecules that serve as building blocks in living systems. In a broader sense, the term has been used to refer to efforts to "redesign life."
• Synthetic biology projects frequently aim to redesign organisms so that they produce a substance, such as a medicine or fuel, or gain a new ability, such as sensing something in the environment.

What is the difference between Synthetic Biology and Genome Editing?

• Synthetic biology is similar to another approach known as "genome editing" in that both involve changing an organism's genetic code; however, some people distinguish between the two approaches based on how that change is made.
• In synthetic biology, scientists typically join together long stretches of DNA and insert them into the genome of an organism.
  • These synthesised DNA fragments could be genes found in other organisms or completely novel.
• Scientists typically use tools to make smaller changes to the organism's own DNA when genome editing.
  • Small stretches of DNA in the genome can also be deleted or added using genome editing tools.

Applications of Synthetic Biology

• Biofuel production: Could be used to create microorganisms capable of producing biofuels efficiently from renewable feedstocks such as plant material or waste products.
• Natural Product Synthesis: Engineers microbes to produce all of the enzymes and biological functions required to perform complex multistep natural product production.
  • Bioremediation uses microorganisms to remove pollutants from our water, soil, and air.
• Medicine: Synthetic biology could be used to create new drugs and therapies like vaccines and cancer treatments.
• Industrial chemicals: Could be used to produce industrial chemicals such as plastics or detergents in a more environmentally friendly and cost-effective manner.
• Applied Protein Design is the process of redesigning existing biological parts and expanding the set of natural protein functions for new processes.
  • Rice has been genetically modified to produce beta-carotene, a nutrient commonly associated with carrots that helps prevent vitamin A deficiency.
• Cleanup of the environment: This could be used to create microorganisms that can clean up pollution or restore damaged ecosystems.
• Agriculture: Synthetic biology could be used to boost crop yields, develop drought-resistant crops, and create pest and disease-resistant crops.
• Synthetic Genomics is the process of designing and building a 'simple' genome for a natural bacterium.
  • Yeast engineered to produce rose oil as an environmentally friendly and sustainable alternative to real roses used by perfumers to create luxury scents.
• Research and development: Synthetic biology can be used to better understand fundamental biological processes, leading to new insights and innovations in a wide range of fields.
• Identify and categorise standardised genomic parts that can be used (and quickly synthesised) to build new biological systems.

Challenges Related to Synthetic Biology

• Technical difficulties: This involves the design and construction of complex biological systems, which can be difficult. Improved tools and technologies are required to enable the precise and reliable design and construction of synthetic biological systems.
• Regulatory issues: Because there is a lack of clear and consistent regulation for synthetic biology, researchers and companies may find it difficult to navigate the field.
• Ethical concerns: This will raise a number of ethical concerns, such as the possibility of negative environmental consequences or concerns about the ethical implications of creating genetically modified organisms.
• Social issues: There is a lack of public understanding and acceptance of synthetic biology, which could stymie its development and implementation. Synthetic biology has the potential to have a negative impact on industries or job markets, as well as exacerbate existing socioeconomic inequalities.
• Funding issues: This research can be costly and time-consuming, and obtaining funding can be difficult.
• Intellectual property issues: Because the field of synthetic biology is rapidly evolving, there is an ongoing debate about intellectual property rights and who should have access to the field's technologies and tools.

Negative Impact of Synthetic Biology

• Safety: Synthetic biological systems have the potential to behave in unexpected ways, which could have negative consequences. For example, genetically modified organisms (GMOs) used in agriculture may have unintended environmental consequences.
• Negative Environmental Health: The deliberate or unintentional release of genetically engineered organisms into the environment could have serious consequences for both human and environmental health.
• Misapplication of these technologies, as well as a failure to account for unintended consequences, could result in irreversible environmental damage.
• Do-It-Yourself Biology: A movement of "citizen scientists" interested in synthetic biology experiments that has grown into an international phenomenon in the last decade.
• With little prior knowledge of the field, enthusiasts gather in makeshift labs to take biotechnology crash courses and conduct hands-on experiments.
• Security: Synthetic biology has the potential to be used maliciously, such as in the development of bioweapons.
• Concerns about ethics: There are ethical concerns about the use of synthetic biology, such as the possibility of creating genetically modified organisms that could have a negative impact on biodiversity or the fear that it could result in "designer babies."
• There is a lack of public understanding and acceptance of synthetic biology, which could stymie its development and implementation.

Synthetic Biology – Positives & Negatives

Synthetic Biology in India

• Synthetic biology, like any other emerging technology, has both positive and negative implications.
• Countries such as India are caught in a quandary in which the industry is investing in developing organisms and products with little regulatory or policy oversight.
• For a country like India, a conceptual framework for the potential future implications of synthetic biology would include elements of inclusion and public responsiveness.
• Such an approach may be novel in India, which has traditionally relied on reactive responses in policymaking and legal framework development.
• Furthermore, the number of interventions undertaken by the private sector in India to focus on product development using synthetic biology is surprising.
• India's policy and regulatory framework must prioritise the following:
  • Determining what constitutes synthetic biology science?
  • What kinds of R&D priorities will be established for the public sector?
  • What will be the future guidance for the private sector in synthetic biology research that takes into account all relevant policy frameworks, including those governing intellectual property rights?
  • How India will regulate the development and use of this technology, taking into account environmental and socioeconomic concerns?

Synthetic Biology – Way Forward

• Synthetic biology is regarded as one of the top ten breakthrough technologies in the ongoing fourth industrial revolution, and is said to be "most likely to change the world".
• While there are "complex challenges" in developing a national regulatory framework, the potential benefits far outweigh the mostly manageable risks.
• The department's document calls for not only a regulatory policy and framework, but also the definition and scope of synthetic biology.
• Stringent risk assessment and the inclusion of diverse stakeholder perspectives should be used in the development and handling of innovative synthetic biology applications and products in accordance with the precautionary principle.
• It is time for India to solidify its position on synthetic biology science and communicate its interests and aspirations in relevant international fora with clarity, avoiding conflicting positions on science on the one hand and policy on the other.
• It is more important than ever to develop a synthetic biology policy because the field is rapidly evolving, with new discoveries occurring every year.
• Soon, we will see some products, and we must be prepared with a regulatory framework.

Conclusion

Synthetic Biology provides novel approaches for creating new biological systems or redesigning existing ones for practical applications. India provides a classic example of how science-policy interface should or should not work, with the Department of Biotechnology and Ministry of Agriculture supporting promotion of this science and technology, and the Ministry of Environment dealing with approval for commercialization of such new technology. However, India has yet to formally develop its national synthetic biology strategy. In the absence of such a strategy, India risks having the same contentious debates about synthetic biology organisms as it does about genetically modified organisms.
