Question

When the genotype of an organism is improved by the addition of foreign gene, the process is called as
A) Tissue culture
B) Genetic diversity
C) Genetic engineering
D) Plastic surgery

Answer 1

Hint: -The genotype of an organism defines the complete set of genetic material. The genotype of an organism is expressed when the DNA of an organism is transcribed and translated into RNA and proteins that play important roles.

Complete answer-
Among the given options in the question, tissue culture is known to be the growth of tissues or cells in an artificial medium and completely separate from the parent organism. Tissue culture can be used for modifying an organism specially plants since they can be easily manipulated and analysed while being grown on a defined medium. Genetic diversity is defined as the total number of genetic variations that exist within a species which differentiates it with other similar species. Genetic engineering is the process by which the genetic makeup of an organism is altered using recombinant DNA technology by addition of foreign genes. Plastic surgery is a surgical procedure that leads to reconstruction, restoration or alteration of the human body in response to some accident or distortion.

So the correct option is C) Genetic engineering.

Note-
Genetic engineering is a highly important technique that has been applied to research, medicine, agriculture as well as industrial biotechnology. In humans they are known to treat different diseases as well as produce certain drugs, hormones and vaccines. Discovery of genetically modified crops have also helped farmers in different countries.
