Option (3) is the correct answer because the cutting of DNA at specific location became possible with the use of restriction enzymes. So, they are also called molecular scissors. The DNA fragments can be joined together by using DNA ligase. They are called molecular glue. DNA polymerase helps in the extension step of PCR.
Which of the following can act as molecular scissors?

The blue and white selectable markers have been developed which differentiate recombinant colonies from non-recombinant colonies on the basis of their ability to produce colour in the presence of a chromogenic substrate. Given below are two statements about this method: Statement I : The blue coloured colonies have DNA insert in the plasmid and they are identified as recombinant colonies. Statement II : The colonies without blue colour have DNA insert in the plasmid and are identified as recombinant colonies. In the light of the above statements, choose the most appropriate answer from the options given below:
