Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The process in which large numbers of identical recombinant DNA molecules are produced is called?
A
test cross
B
selective breeding
C
transgenic organism
D
cloning
Explanation: 

Detailed explanation-1: -DNA cloning is a molecular biology technique that makes many identical copies of a piece of DNA, such as a gene.

Detailed explanation-2: -recombinant DNA technology / DNA cloning; gene cloning; cloning. A technology that uses enzymes to cut and paste together DNA sequences of interest. The recombined DNA sequences can be placed into vectors that carry the DNA into a host cell.

Detailed explanation-3: -The use of the word clone has been extended to recombinant DNA technology, which has provided scientists with the ability to produce many copies of a single fragment of DNA, such as a gene, creating identical copies that constitute a DNA clone.

Detailed explanation-4: -Molecular cloning is the laboratory process used to create recombinant DNA. It is one of two most widely used methods, along with polymerase chain reaction (PCR), used to direct the replication of any specific DNA sequence chosen by the experimentalist.
