The palindromic base sequence is a sequence in double-stranded nucleic acids that reads the same on both strands when reading one strand from left to right and the other from right to left (ie, both strands are read 5′→3 ). Out of the given options 5′− GAATTC-3 3-CTTAAG-5 is a palindromic sequence that can be cut at about the middle by particular restriction enzyme.
Which one of the following palindromic base sequences in DNA can be easily cut at about the middle by some particular restriction enzyme?

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:
