Vedclass · Answer

(A) Restriction enzymes recognize specific palindromic nucleotide sequences in $DNA$ to perform cleavage.$A$ palindromic sequence in $DNA$ is a sequence of base pairs that reads the same on the two strands when the orientation of reading is kept the same (e.g.,$5' \rightarrow 3'$).Option $A$ $(5'-GAATTC-3'; 3'-CTTAAG-5')$ represents the recognition site for the restriction enzyme $EcoRI$.This sequence is a perfect palindrome because the sequence $GAATTC$ read from $5' \rightarrow 3'$ on one strand is identical to the sequence $GAATTC$ read from $5' \rightarrow 3'$ on the complementary strand.Options $B$,$C$,and $D$ do not represent standard palindromic sequences recognized by common restriction enzymes.
