Detailed explanation-1: -In order to create transgenic swine, one-and/or two-cell ova must be recovered, injected with DNA and subsequently transferred back to suitable recipients. The developmental capacity of porcine one-and two-cell ova in various media has been reviewed by Wright and Bondioli (1981).
Detailed explanation-2: -The most common method for producing transgenic animals is gene transfer by DNA microinjection, which involves the following steps: DNA containing the desired transgene is identified and cloned (copied tens of thousands of times in bacteria) before insertion into the animal host.
Detailed explanation-3: -The pig is genetically engineered to eliminate the presence of alpha-gal, a type of sugar found in many mammals. The sugar makes its way into many products-including medications, cosmetics and food-and can cause allergic reactions in some people.
Detailed explanation-4: -Genetically modified pigs can be used as organ donors for xenotransplantation.
