In the modern day, gene synthesis is the biotechnological method of engineering artificial genes in a laboratory setting, transforming molecular biology by allowing researchers to create genes and even entire genomes from the ground – up. The procedure has also revolutionized traditional methods of studying genetics and introduced some intriguing changes.
This technology has numerous applications in biotechnology, medicine, agriculture, and environmental science. Below are ways in which gene synthesis has advanced over the years, as well as the application of these new advancements. Read on for more information.
1. Synthetic Biology
The process of creating genes chemically from scratch is known as gene synthesis and is a synthetic biology technology. By using this technique, scientists can produce distinctive DNA sequences that can be utilized to investigate gene function or develop novel biological systems.
Gene synthesis begins with the creation of a DNA strand using computer tools. After that, the sequence is broken up into smaller chunks that may be chemically produced using common techniques for DNA synthesis. These artificial DNA pieces are combined into a larger gene using specialized enzymes.
Synthesizing genes has revolutionized synthetic biology, allowing scientists to create previously undiscovered biological systems. Researchers, for example, have used gene synthesis to create microbes that generate alternative energy sources and crops that can thrive in harsh conditions.
Gene therapy, a field of medicine that aims to treat genetic illnesses by substituting or fixing defective genes, has also been revolutionized by gene synthesis. Personalized DNA fragments are synthesized, and researchers can develop new treatments that are specifically suited to the demands of each patient.
2. Protein Engineering
Gene synthesis is an effective tool in protein engineering for designing and producing novel proteins with desirable properties. Moreover, it can be used in protein engineering to create entirely new proteins or to modify existing ones by introducing specific mutations or amino acid substitutions. This can be done to improve a protein’s stability, solubility, or activity or introduce entirely new functions into a protein.
The required protein can be generated using a cell-free protein enzyme system, e.g., yeast after the gene sequence has been constructed. The protein can then be isolated and studied to learn more about its characteristics and how it works.
In general, gene synthesis is a potent tool for protein engineering that has produced numerous unique proteins with various uses in biotech, healthcare, and other areas.
3. Vaccine Development
Synthesizing genes aids in vaccine development by generating vaccine antigens from recombinant proteins. Gene synthesis generates genes encoding antigens from pathogens or viruses. These genes can then be placed into expression constructs to produce recombinant proteins that emulate the surface antigens of the pathogen.
Vaccines can then be made from the recombinant proteins created through gene synthesis. The receiver’s immune system detects the conjugated protein as foreign and generates an immune reaction against it, resulting in pathogen immunity. This method has been used successfully to develop vaccines for various diseases, including hepatitis B, human papillomavirus (HPV), and influenza.
4. Agricultural Biotechnology
Gene synthesis is a powerful agricultural technology tool that enables researchers to create customized genetic variants that can be introduced into crops to induce desirable characteristics such as disease resistance, drought tolerance, and increased yield.
By synthesizing genes, scientists eliminate limitations placed on conventional breeding techniques. They are known to be sluggish and inaccurate. With gene synthesis, scientists may make DNA fragments that specifically target particular genes and enable them to develop crops with specialized properties.
For example, gene synthesis has been used to develop pest and disease-resistant crops, such as the Rainbow papaya, which was genetically modified to resist the fatal papaya ringspot virus.
All in all, gene synthesis is an essential tool in agricultural technology that has the potential to revolutionize plant breeding and aid in the resolution of worldwide nutritional challenges.
5. Gene Therapy
Gene synthesis is used in gene therapy to generate new genes or modify existing ones to treat genetic abnormalities.
Therapeutic genes are created, then delivered to the patient’s cells via various methods, including viral vectors and non-viral delivery methods. Once inside the cells, the therapeutic genes can correct or replace the disease-causing genes.
However, this approach has risks and challenges, such as the possibility of unintended effects or immune responses to the introduced genes. As a result, extensive testing and regulatory approval are required before synthesized gene therapy can be approved for clinical use.
6. Environmental Applications
There are several potential applications for gene synthesis in environmental science and biotechnology, including:
Creating recombinant enzymes: Gene synthesis can create genes that encode for recombinant enzymes with desirable properties for bioremediation or other environmental applications. Enzymes, for example, can be designed to degrade persistent organic pollutants (POPs) or other toxic compounds.
Developing genetically modified organisms (GMOs): Gene synthesis can create organisms with specific characteristics useful for the effluent treatment or other purposes.
Generally speaking, gene synthesis has the potential to transform environmental science and biotechnology by providing researchers with powerful instruments to tackle environmental challenges and develop long-term solutions. However, as with any new technology, gene synthesis’s potential risks and ethical implications in environmental applications must be carefully considered.
Bottomline
The development of gene synthesis technology has transformed our understanding of how DNA functions as the blueprint for life, as well as our capacity to alter DNA for experimental, medical, and industrial purposes. With advancements in automation, error correction, and cost-effectiveness, gene synthesis will become a valuable tool for many scientific specialties and economically significant applications. The next decade will undoubtedly provide fascinating new prospects for gene synthesis to drive advancements in the biological sciences.
