Discuss the development of a novel protein.
Show Hint
Solution and Explanation
(i) Development of a novel protein: Recombinant vaccine based on selected epitope: To develop a novel protein using recombinant DNA technology, it is first necessary to select an epitope, which is a specific portion of a protein of a virus that can create an immune response. A synthetic gene for the selected epitope is assembled, and introduced into a host cell, like bacteria or yeast. These host cells are grown on a large scale. Then the epitope protein is isolated and purified for use as a recombinant vaccine, or as a subunit vaccine.
(ii) Properties that can be manipulated using Protein Engineering: Using Protein Engineering techniques, various properties of proteins can be modified, and some of these include: Thermal stability: The protein can be modified to make it stable at higher temperatures. pH stability: The protein can be modified to make it stable in a wider range of pH. Solvent tolerance: This allows the protein to function effectively in the presence of various solvents. Solubility: It is possible to manipulate the solubility of the protein. Catalytic Potency: This enables one to enhance the catalytic activity of a protein. Biological adaptation to environmental stresses: Using protein engineering, proteins can be manipulated to increase their tolerance to various stresses, such as high salinity, drought, and extreme temperatures.

- Ankur Sachdeva did his MBA from ITB University. He decided to apply his knowledge of scientific management in the fast food restaurant chain 'Coffee Bean' set up by him. This restaurant was providing burgers, fries, shakes etc, as a part of its menu. Nowadays people are quality conscious, so he was using standardised raw materials, processes, methods, working conditions, machinery etc. The objective was to establish standards of excellence. By doing this he was not only able to reduce the cost but was also able to provide new varieties of burgers, fries and shakes leading to increased turnover. Ankur Sachdeva also believed that there was only one best method to maximise efficiency. As a result he developed best way of grilling burgers, cooking fries and preparing shakes. His main objective was to maximise the satisfaction of customers, which he was able to achieve. Not only to learn the best way of doing a job, but to perform their tasks efficiently, 'Coffee Bean' regularly invests in training and development programmes to equip employees with the necessary skill and knowledge. 'Coffee Bean' believed that efficient employees will produce more and earn more. This will ensure their greatest efficiency and prosperity for both company and workers. The above case highlights the use of Scientific principles and techniques by 'Coffee Bean'. Explain any one such principle and two techniques.

- Preeti started her own cooking channel on 'Youtube Mood Art'. As her subscribers increased, she was not in a position to manage everything on her own. She hired Rahul and Riya to help her with filming editing, lighting and content research. She granted authority to them to operate within prescribed limits. She was thus, able to use her time on high priority activities like developing new recipes and content development etc. As a result, Rahul and Riya were given opportunities to develop and exercise initiative. Preeti was now able to focus on objectives and meet the target of achieving a subscriber base of one million in six months.
