Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is recombinant DNA?
A
DNA containing genes foreign to that organism
B
DNA which has been impacted by epigenetics
C
DNA that has restriction enzymes
D
DNA that has been sequenced
Explanation: 

Detailed explanation-1: -Recombinant DNA technology is the joining together of DNA molecules from two different species. The recombined DNA molecule is inserted into a host organism to produce new genetic combinations that are of value to science, medicine, agriculture, and industry.

Detailed explanation-2: -A transgenic, or genetically modified, organism is one that has been altered through recombinant DNA technology, which involves either the combining of DNA from different genomes or the insertion of foreign DNA into a genome.

Detailed explanation-3: -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. The resulting copies are often referred to as recombinant DNA.

Detailed explanation-4: -In recombinant technologies, the desired gene selected which is followed by selecting a perfect vector into which the desired gene has to be integrated and then recombinant DNA is formed by ligating the gene of interest with the vector.

Detailed explanation-5: -An organism that receives the recombinant DNA is called a genetically modified organism (GMO). If the foreign DNA that is introduced comes from a different species, the host organism is called transgenic.
