Detailed explanation-1: -Methods of base editing are under development in which a “nuclease-dead” Cas 9 endonuclease or a related enzyme is used for gene targeting while a linked deaminase enzyme makes a targeted base change in the DNA. The most recent refinement of CRISPR-Cas9 is called Prime Editing.
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: -Transgene: A gene from one organism inserted into another organism by recombinant DNA techniques. Transgenic organism: An organism resulting from the insertion of genetic material from another organism using recombinant DNA techniques.
Detailed explanation-4: -Genetic engineering, also known as genetic modification, enables scientists to transfer genes from one organism to another. Humans, animals, and plants are examples of these organisms. Thus, genetic modification refers to the transfer of desired genes from one organism to another.
