Detailed explanation-1: -Definition. 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, also called as genetic modification is the direct manipulation of an organism’s genome using biotechnology. It is a set of technologies used to change the genetic make up of cells, including the transfer of genes within and across species boundaries to produce improved or novel organisms.

Detailed explanation-3: -Genetic engineering is defined as the direct manipulation of an organism’s genes including heritable and nonheritable recombinant DNA constructs.

Detailed explanation-4: -Genetic engineering is accomplished in three basic steps. These are (1) The isolation of DNA fragments from a donor organism; (2) The insertion of an isolated donor DNA fragment into a vector genome and (3) The growth of a recombinant vector in an appropriate host.
