Synthetic biology is an advanced field that combines biology and engineering to design and construct new biological systems, or to redesign existing biological systems for useful purposes. Unlike traditional genetic engineering, which typically involves modifying existing organisms by adding or altering a few genes, synthetic biology often involves creating entirely new genetic sequences from scratch.
Synthetic biology takes a more systematic and engineering-based approach, aiming to create standardised biological components that can be assembled in a modular way. The most notable example of synthetic biology can be shown in the synthetic yeast project. In this project, the researchers aim to create the entire yeast genome in the lab and are successful in creating 7 out of 16 chromosomes entirely in lab.
Traditional genetic editing involves modifying existing organisms by altering or adding specific genes to achieve desired traits or functions. This approach is focused on making targeted changes to the genetic makeup of an organism to enhance specific traits or functions. On the other hand, synthetic biology takes a broader approach by designing and constructing new biological systems.

Recombinant DNA technology has revolutionized the production of insulin, making it more efficient and scalable. This biotechnology involves the insertion of the human insulin gene into bacterial DNA, enabling bacteria to produce insulin identical to that naturally produced by the human body.
Here’s how it works:
1. **Gene Isolation**: The human insulin gene is isolated using restriction enzymes, which cut DNA at specific sequences.
2. **Plasmid Insertion**: The isolated insulin gene is inserted into a plasmid (a small circular DNA molecule) using DNA ligase, which seals the gene into the plasmid. Plasmids serve as vectors to transfer genetic material.
3. **Transformation**: The recombinant plasmid is introduced into Escherichia coli (E. coli) bacteria. This process, called transformation, allows the bacteria to take up the plasmid and incorporate it into their own DNA.
4. **Cultivation**: The genetically modified bacteria are cultivated in large fermentation tanks. As the bacteria grow and divide, they express the insulin gene, producing human insulin.
5. **Extraction and Purification**: The insulin is then harvested from the bacterial cultures and purified to ensure it is free from contaminants and suitable for medical use.
This method, pioneered in the 1980s, replaced the previous reliance on animal-derived insulin, which was less efficient and posed higher risks of allergic reactions. Recombinant DNA technology has thus enabled the mass production of high-quality, human-compatible insulin, significantly benefiting people with diabetes worldwide.

During a recession, companies lay off employees primarily to manage costs and ensure survival. Revenue drops as consumer spending decreases, prompting businesses to reduce expenses, and labor is one of the largest costs. Layoffs help immediately cut payroll expenses and preserve cash flow, which is crucial during economic uncertainty.
With lower demand for products and services, companies need fewer employees. Aligning the workforce with reduced demand helps maintain operational efficiency. Additionally, recessions often trigger restructuring efforts to streamline operations and eliminate redundancies, further driving layoffs.
Publicly traded companies face investor pressure to maintain profitability and protect stock prices. Layoffs signal decisive cost management, reassuring investors about the company’s financial health. For some businesses, layoffs are essential to avoid bankruptcy, ensuring they can continue operations during the downturn.
While layoffs are common, they can harm employee morale, company reputation, and long-term performance. Some companies explore alternatives like reducing executive salaries, cutting non-essential expenses, or implementing temporary furloughs to mitigate these impacts. Ultimately, layoffs are a strategic move to balance immediate cost reduction with the goal of emerging stronger post-recession.
