Detailed explanation-1: -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-2: -DNA molecules produced by splicing together two or more DNA fragments are called recombinant DNA molecules; they have made possible many new types of cell-biological studies.
Detailed explanation-3: -Recombinant DNA, which is often shortened to rDNA, is an artificially made DNA strand that is formed by the combination of two or more gene sequences. This new combination may or may not occur naturally, but is engineered specifically for a purpose to be used in one of the many applications of recombinant DNA.
