Detailed explanation-1: -Foreign DNA is inserted into a plasmid (or any cloning vector) by ligating the DNA into a complementary site in the plasmid. These sites are generated by digesting the DNA and vector with the same restriction enzyme. (The site for the restriction enzyme that is chosen should only be represented once in the plasmid.
Detailed explanation-2: -Plasmids with foreign DNA inserted into them are called recombinant DNA molecules because they contain new combinations of genetic material.
Detailed explanation-3: -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-4: -Packaging foreign DNA for bacteria Most vectors are based on plasmids, which are small circular sequences of DNA that occur naturally within bacteria. Plasmid vectors can accept a few genes’ worth of DNA. Others, called bacterial artificial chromosomes or BACs, can contain much longer DNA sequences.
