Answer:
GGATCC
CCTAGG.
Step-by-step explanation:
Pallindromic sequence may be defined as the sequence of the nucleotides that reads in the certain direction on which the strand reads and they are complementary to each other.
These sequences when read in 5' to 3' direction, the sequence is similar from 3' to 5' direction as well. The sequence GGATCC when reads from the oppposite direction results in the same sequence CCTAGG. Hence, these are pallindromic sequences.
Thus, the correct answer is option (d).
