Restriction Endonuclease is a type of restriction enzyme that cuts within the DNA at a specific site. This enzyme acts as an important tool in genetic engineering for cutting DNA sequences from a specific site. They play an important role in gene manipulation. Exonuclease refers to an enzyme that cleaves. polynucleotide chain from the end of the chain by removing the nucleotides one by one. They cleave nucleic acids at the ends and result in single nucleotides. They form blunt ends.

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:
