Detailed explanation-1: -The correct answer is (A) a fragment of DNA composed of sequences originating from at least different sources. Recombinant DNA is formally defined as a DNA molecule which contains nucleotide sequences from two or more different organisms.
Detailed explanation-2: -Recombinant DNA Technology is defined by the Encyclopedia Britannica as “the joining together of DNA molecules from different organisms and inserting it into a host organism to produce new genetic combinations that are of value to science, medicine, agriculture and industry.”
Detailed explanation-3: -Which term describes DNA that has been altered by genes from a different organism, typically from a different species? Explanation: Recombinant DNA are segments of DNA from one organism artifically manipulated or inserted into the DNA of another organism, using a technique known as gene splicing.
Detailed explanation-4: -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-5: -They shorten the DNA by one nucleotide at a time, they do not digest it into fragments. Thus the correct answer is option D.
