    3'CTTAAG-5'

  • 5'-GAATTC-3'
    3'CTTAAG-5'


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.
