Write a note on vectors used during recombinant DNA technology. Draw diagram of any two vectors
A vector or vehicle DNA is used as carrier for transferring selected DNA into cells. A plasmid with its small DNA from a bacterium is a good choice for indirect gene transfer, because it can move from one cell to another and make several copies of itself. However, artificial chromosomes from bacteria and yeast called BACs and YACs respectively are more efficient for eukaryotic gene transfers.
