1.	In recombinant DNA technology, the term vector refers toA. the enzyme that cuts DNA into restriction fragmentsB. the sticky end of a DNA fragmentC. a plasmid used to transfer DNA into a living cellD. a DNA fragment which carries only ori gene
Answer» Correct Answer - C The DNA used as a carrier for transferring a fragment of forign DNA into a suitable host is called vehicle DNA or cloning vector or gene carrier. When desired gene is introduced into a vector, recombinant DNA is formed. Vectors may be plasmids, bacteriophages, cosmids, phagemids, Yeast Artificial Chromosomes (YACs), Bacterial Artificial Chromosomes (BACs), transposons, viruses. etc.
