Question

How is copy number of plasmid vector related to the yield of recombinant protein?

Answer 1

The recombinant DNA can multiply as many times as the copy number of the plasmid vector, thereby determining the yield of recombinant protein. So, higher the copy number of the plasmid vector, higher will be yield of recombinant protein. Therefore Copy number of plasmid is directly related to copy number of gene for coding and producing the recombinant protein.
