Define genetic engineering? Write the advantage's of genetic engineering?
Answers
Answer:
Genetic engineering, also called genetic modification or genetic manipulation, is the direct manipulation of an organism's genes using biotechnology
Advantages of genetic engineering:
More nutritious food.
Tastier food.
Disease- and drought-resistant plants that require fewer environmental resources (such as water and fertilizer)
Less use of pesticides.
Increased supply of food with reduced cost and longer shelf life.
Faster growing plants and animals.
Answer:
(a) Genetic engineering is the modification of the genetic information of living organisms by manipulation of DNA by adding, removing or repairing part of the genetic material (DNA) and changing the phenotype of the organism.
It is also known as gene manipulation or recombinant DNA Technology (r-DNA Technology).
(b) Advantages of genetic engineering includes-
(i) Studying gene structure and function.
(ii) Production of large quantities of insulin, interferon, human growth hormones, vaccines, etc.
(iii) It is used to transfer of nif genes involved in Nitrogen fixation to increase yield.
