Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which best describes the technique of genetic engineering?
A
Manufacturing synthetic DNA in the laboratory from chemicals.
B
cutting out segments of the DNA of an organism under a microscope
C
exposing the DNA of an organism to radioactivity to produce mutations
D
introducing foreign DNA into an organism in order to modify the organism’s DNA
Explanation: 

Detailed explanation-1: -Transduction is the process by which foreign DNA is introduced into a cell by a virus or viral vector. Genetically modified viruses can be used as viral vectors to transfer target genes to another organism in gene therapy. First the virulent genes are removed from the virus and the target genes are inserted instead.

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: -Transgenic Transgenic refers to an organism or cell whose genome has been altered by the introduction of one or more foreign DNA sequences from another species by artificial means. Transgenic organisms are generated in the laboratory for research purposes.

Detailed explanation-4: -Recombinant DNA: DNA which has been altered from its original form by joining genetic material from two different sources. It usually involves putting a gene or part of a gene obtained from one organism into the genome of a different organism.

Detailed explanation-5: -genetic engineering, the artificial manipulation, modification, and recombination of DNA or other nucleic acid molecules in order to modify an organism or population of organisms.
