The construction of first artificial recombinant DNA molecule was by:

The linking of the antibiotic resistance gene with the plasmid vector became possible with:

E. coli cloning vector $\mathrm{pBR}322$ contains restriction sites (Hind $\mathrm{III}$, $$EcoR $\mathrm{I}$, BamH $\mathrm{I}$, Sal $\mathrm{I},$ Pvu $\mathrm{II},$ Pst $\mathrm{I},$ Cla $\mathrm{I}$)- ori, amp ${\mathrm{amp}}^{\mathrm{R}}, t{\mathrm{et}}^{\mathrm{R}},$ and $\mathrm{rop}$. $\mathrm{rop}$ codes for the

In the process of recombinant DNA technology, the isolated foreign DNA is inserted into another DNA molecule known as 

"Molecular Scissors" used in genetic engineering is

Transfer of DNA bands from an agarose gel to a nitrocellulose or nylon membrane is referred to as:

*Note: The options are modified here.

In biotechnology applications, a selectable marker is incorporated in a plasmid

Restriction endonucleases are enzymes that are used by biotechnologists to
