C.
5'-GAATTC-3'
3'CTTAAG-5'
The palindromic base sequence is a sequence in double -stranded nucleic acids that read the same on both strands when reading one strand from left to right and the other from right to left (i.e both strands 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 a particular restriction enzyme.
