Q6. Could you detail the PCR technique’s critical role in contemporary biotechnology?

Answer: Polymerase Chain Reaction (PCR) is a fundamental technique in biotechnology that amplifies specific DNA sequences, making it possible to generate millions of copies from a small sample. The PCR technique unfolds through three primary stages: denaturation, annealing, and extension, starting with separating DNA strands at high temperatures. Next, primers anneal to specific target sequences at a lower temperature. Finally, a DNA polymerase extends the primers, duplicating the DNA. The significance of PCR in modern biotechnology cannot be overstated—it underpins diagnostic tests, genetic fingerprinting, and the cloning of genes. For instance, during the recent global health crisis, PCR was instrumental in detecting viral RNA quickly and accurately, proving essential for monitoring and controlling disease spread.

 Q7. Discuss when you had to develop a solution to a problem in a laboratory setting. What was the outcome?

Answer: In my previous role at a pharmaceutical company, we encountered repeated failures in synthesizing a stable protein needed for a new drug. The protein would degrade rapidly, rendering it unusable for further testing. To address this, I spearheaded a team to modify the protein’s structure through site-directed mutagenesis to enhance its stability without compromising its activity. We systematically tested various mutations and found a variant that maintained its functional integrity while being significantly more stable under our experimental conditions. This breakthrough facilitated the drug development process and led to a patent filing for the new protein variant, considerably contributing to the project’s success and my team’s understanding of protein engineering. 

Q8. What distinguishes gene expression in prokaryotic cells from eukaryotic cells?

Answer: The fundamental differences between prokaryotic and eukaryotic gene expression are rooted in their cellular structures and regulatory mechanisms. In prokaryotes, gene expression is typically straightforward, occurring in the cytoplasm with little to no post-transcriptional modification, and often involves polycistronic mRNA, which can encode multiple proteins from a single mRNA transcript. Conversely, eukaryotic cells undergo complex gene expression steps with their compartmentalized structure, including chromatin remodeling, transcription, RNA splicing, and post-translational modifications. These processes allow for a highly regulated and versatile expression system but also introduce multiple levels of control and potential points of regulation, which are critical for ensuring cellular function and adaptability in diverse environments. Understanding these differences is crucial for any biotechnological application, from microbial fermentation to human gene therapy, each requiring specific strategies tailored to the cellular expression systems involved.

 Q9. How do bioreactors work? Describe the key considerations in designing a bioreactor for a new product.

Answer: Bioreactors are vessels in which biological reactions are carried out, especially for cultivating microorganisms or cells under controlled conditions to manufacture biological products such as pharmaceuticals, chemicals, or food ingredients. Bioreactors’ functioning is centered around controlling environmental variables like temperature, pH, oxygen, and nutrients to enhance the growth and efficiency of the biological entities involved. Key considerations in designing a bioreactor include the type of organism or cells used, the desired product, the mode of operation (batch, fed-batch, or continuous), and the production scale. For instance, when developing a bioreactor for a new antibiotic, it’s crucial to ensure efficient oxygen transfer and mixing capabilities, as these can significantly impact cell growth and metabolite production. Material compatibility and sterilization methods must also be considered to prevent contamination and ensure consistent product quality.

 Q10. What role does bioinformatics play in your daily work? Can you give a specific example?

Answer: Bioinformatics is integral to my role, especially in managing and analyzing vast datasets derived from genomic and proteomic studies. For example, in a recent project on identifying novel drug targets for cancer therapy, I used bioinformatics tools to analyze gene expression profiles and identify potential biomarkers for specific cancer types. This involved using software like BLAST for sequence alignment and R packages for statistical analysis to interpret the data effectively. The insights gained expedited our target validation process and enhanced our strategic decision-making by pinpointing the most promising candidates for further investigation. Bioinformatics thus serves as a critical bridge between biological data and practical applications in drug development.
