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: -Genome editing is a way of making specific changes to the DNA of a cell or organism. An enzyme cuts the DNA at a specific sequence, and when this is repaired by the cell a change or ‘edit’ is made to the sequence.
Detailed explanation-3: -Locating an organism with a specific trait and extracting its DNA. Cloning a gene that controls the trait. Designing a gene to express in a specific way. Transformation, inserting the gene into the cells of a crop plant. Cross the transgene into an elite background.
