Azotobacter
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The Ti plasmid, utilized in the creation of transgenic plants, is located within the bacterium Agrobacterium tumefaciens. This plasmid serves as a vehicle for transferring genes into plant cells. Within the Ti plasmid, there are two main regions: the vir region, which is responsible for conferring virulence toward the host, and the tDNA region, which is the portion transferred to the host plant.

Biotechnology
Biotechnology is a vast field of biology that involves the creation, production, and modification of useful products for human welfare using both the technology and the execution of living organisms and their components. An agricultural engineer, Karoly Ereky, coined the word "biotechnology" in 1919, achieving him the title of "Father of Biotechnology."
Principles of Biotechnology:
Among many, the two core techniques that entitled the birth of modern biotechnology are :
- Genetic Engineering is one of the methods of direct modifications of an organism's genome (i.e., DNA and RNA). It requires the introduction of new genes into host species to escalate function or trait, hence altering the host organism's phenotype.
- Bioprocess Engineering is one of the methods of maintaining sterile conditions to facilitate the growth of large quantities of desired microbes and other eukaryotic cells for the development of new or modified biotechnological products such as enzymes, vaccines, antibiotics, and other biotechnological products.
