Which one of the following represents palindromic sequence in DNA?

A $5^{'} - GATACC - 3^{'}; 3^{'} - CCTAAG - 5^{'}$
B $5^{'} - GAATTC - 3^{'}; 3^{'} - CTTAAG - 5^{'}$
C $5^{'} - CCAATG - 3^{'}; 3^{'} - GAATCC - 5^{'}$
D $5^{'} - CATTAG - 3^{'}; 3^{'} - GATAAC - 5^{'}$

Solution & Step-by-step Explanation

A palindromic sequence reads the same on both strands when read in the same direction (5^{'} \to 3^{'}).In Option B:Top: 5^{'} - GAATTC - 3^{'} Bottom (5^{'} \leftarrow 3^{'}): 5^{'} - GAATTC - 3^{'} This is the recognition site for EcoRI.
