Detailed explanation-1: -In 1972, Paul Berg started genetic engineering. With the aid of the lambda phage, he was able to insert the SV-40 virus gene into the bacterium. Berg is also called the “Father of Genetic Engineering”. He was awarded the 1980 Nobel Prize.
Detailed explanation-2: -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-3: -Genetic engineering allows scientists to select one specific gene to implant. This avoids introducing other genes with undesirable traits. Genetic engineering also helps speed up the process of creating new foods with desired traits.
Detailed explanation-4: -Definition. Recombinant DNA technology involves using enzymes and various laboratory techniques to manipulate and isolate DNA segments of interest. This method can be used to combine (or splice) DNA from different species or to create genes with new functions.
