Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Genetic engineering is the modification of the characteristics of an organism by manipulating its genetic material/DNA. Which is an application of genetic engineering?
A
destroying all bacteria
B
creating synthetic insulin
C
producing cells from nonliving material
D
preventing weeds from spreading to farmland
Explanation: 

Detailed explanation-1: -Genetic engineering is the modification of an organism’s phenotype by manipulating its genetic material. Some genetic engineering uses the principle of recombination. Recombination is the process through which a new gene is inserted into a bacterial DNA “The plasmid".

Detailed explanation-2: -Genetic engineering allows scientists to move desired genes from one plant or animal into another. Genes can also be moved from an animal to a plant or vice versa. Another name for this is genetically modified organisms, or GMOs. The process to create GE foods is different than selective breeding.

Detailed explanation-3: -The genetic engineering process The gene for human insulin is inserted into the gap in the plasmid. This plasmid is now genetically modified. The genetically modified plasmid is introduced into a new bacteria or yeast cell. This cell then divides rapidly and starts making insulin.

Detailed explanation-4: -GM is a technology that involves inserting DNA into the genome of an organism. To produce a GM plant, new DNA is transferred into plant cells. Usually, the cells are then grown in tissue culture where they develop into plants. The seeds produced by these plants will inherit the new DNA.
