Vedclass · Answer

(A) palindromic $DNA$ sequence 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.,$5^{\prime} \rightarrow 3^{\prime}$).$1$. Option $A$: $5^{\prime}$-$GTCGTC$-$3^{\prime}$ and its complement $3^{\prime}$-$CAGCAG$-$5^{\prime}$. Reading the complement in $5^{\prime} \rightarrow 3^{\prime}$ direction gives $5^{\prime}$-$GACGAC$-$3^{\prime}$,which is not the same as $5^{\prime}$-$GTCGTC$-$3^{\prime}$. Thus,it is not palindromic.$2$. Option $B$: $5^{\prime}$-$GAATTC$-$3^{\prime}$ and $3^{\prime}$-$CTTAAG$-$5^{\prime}$. Reading the complement in $5^{\prime} \rightarrow 3^{\prime}$ gives $5^{\prime}$-$GAATTC$-$3^{\prime}$,which is palindromic.$3$. Option $C$: $5^{\prime}$-$AAATTT$-$3^{\prime}$ and $3^{\prime}$-$TTTAAA$-$5^{\prime}$. Reading the complement in $5^{\prime} \rightarrow 3^{\prime}$ gives $5^{\prime}$-$AAATTT$-$3^{\prime}$,which is palindromic.$4$. Option $D$: $5^{\prime}$-$GACCTC$-$3^{\prime}$ and $3^{\prime}$-$CTGGAG$-$5^{\prime}$. Reading the complement in $5^{\prime} \rightarrow 3^{\prime}$ gives $5^{\prime}$-$GACCTC$-$3^{\prime}$,which is palindromic.Therefore,option $A$ is the correct answer.
