Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A molecule containing DNA from two different organisms is called
A
a plasmid.
B
a polyploid.
C
a hybrid organism.
D
recombinant DNA.
Explanation: 

Detailed explanation-1: -recombinant DNA, molecules of DNA from two different species that are inserted into a host organism to produce new genetic combinations that are of value to science, medicine, agriculture, and industry.

Detailed explanation-2: -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-3: -Recombinant DNA (rDNA) molecules are DNA molecules formed by laboratory methods of genetic recombination (such as molecular cloning) that bring together genetic material from multiple sources, creating sequences that would not otherwise be found in the genome.

Detailed explanation-4: -Listen to pronunciation. (ree-KOM-bih-nunt) In genetics, describes DNA, proteins, cells, or organisms that are made by combining genetic material from two different sources. Recombinant substances are made in the laboratory and are being studied in the treatment of cancer and for many other uses.

Detailed explanation-5: -Recombinant DNA is DNA that is created by combining DNA from diverse sources. Non-recombinant: There is no genetic recombination in non-recombinants. It is more akin to the original or parent DNA.
