In the following palindromic base sequences of DNA, which one can be cut easily by particular restriction enzyme?
5'GATACT3'; 3'CTATGA5'
5'GAATTC3'; 3'CTTAAG5'
5'CTCAGT3'; 3'GAGTCA5'
5'GTATTC3'; 3'CATAAG5'
Option (2) is the correct answer as a palindromic DNA sequence is a DNA sequence of base pairs that reads same on the two strands when orientation of reading is kept the same. Out of the four options, option (2) is the only palindromic sequence. 5'GAATTC3' / 3'CTTAAG5'
