Maintenance of sterile ambience to enable growth of only desired cell in large quantities for manufacture of biotechnological product is
A. Bioprocess engineering
B. Genetic engineering
C. One of the core technique of modern technology
D. More than one option is correct

Hint: For optimal cell formation, maintaining ideal culture temperatures is essential. The temperature chosen would depend on the origin of the cells that are to be cultured. Fortunately, to ensure that cells are given the best chance of survival and development, there are a variety of temperature solutions available.

Complete answer:
Bioprocess engineering is a form of chemical engineering; it is responsible for the production of biotechnology products, such as food, chemicals, instruments, etc. A bioprocess is a particular method of obtaining desirable goods using full living cells or their components. For several biological and environmental processes, carrying energy and mass is important. Bioprocess engineering plays a major role when a component is processed in large quantities. Chemical, as well as biological engineering, are also used in genetic modification; this method requires the modification of DNA, its components for creating a perfect DNA. Ambient preservation requires preserving a microbial or disease-free culture for the biotechnology phase in order to amplify only the desired gene or cell (multiplying the gene to form a large number of copies).

Hence, the correct answer is option (D).

Additional information:

Note: Bioprocess engineering is responsible for turning into practical goods the findings in life science. In the current multibillion-dollar fermentation industries responsible for the manufacture of ethanol, amino acids, etc., bioprocess engineering also has a major role. The method of using recombinant DNA technologies to change the genetic structure of an organism is genetic engineering. Traditionally, human beings have indirectly manipulated genomes by manipulating breeding and selecting offspring with desired traits.
