Detailed explanation-1: -Genetic engineering (also called genetic modification) is a process that uses laboratory-based technologies to alter the DNA makeup of an organism. This may involve changing a single base pair (A-T or C-G), deleting a region of DNA or adding a new segment of DNA.

Detailed explanation-2: -Genetic engineering is the modification of the genetic information of living organisms by manipulation of DNA i.e. by adding, removing or repairing part of genetic material (DNA) and changing the phenotype of the organism. It is also known as gene manipulation or Recombinant DNA Technology (r-DNA Technology).

Detailed explanation-3: -Genetic engineering, also called genetic modification, is the direct manipulation of an organism’s genome using biotechnology. It is a set of technologies used to change the genetic makeup of cells, including the transfer of genes within and across species boundaries to produce improved or novel organisms.

Detailed explanation-4: -It’s called genetic engineering. It involves cutting a gene from one organism and paste it into the DNA of another. So as to transfer a trait or characteristics. For example, if the insulin gene is cut from a human chromosome and then pasted into a bacterium, then the bacteria can produce human insulin.

Detailed explanation-5: -Genetic engineering refers to the direct manipulation of DNA to alter an organism’s characteristics (phenotype) in a particular way.
