Q. In the given segment DNA strand the base sequence on the opposite strands are same when read in opposite direction. Such sequences are known as
$5’\underline\underline\underline\underline\underline \, GAATTCC \, \underline\underline\underline\underline\underline \, 3’$
$3’\underline\underline\underline\underline\underline \, CTTAAG \, \underline\underline\underline\underline\underline \, 5’$

Solution:

The palindrome in DNA is a sequence of base pairs that reads same on the two strands when orientation of reading is kept the same. For example, the following sequences read the same on the two strands in $5’$ to $3’$ direction. This is also true if read in the $3’$ to $5’$ direction. Such sequences are identified by restriction enzyme for cutting DNA.
