Answer: GGTCTTCAAC
Explanation: To find the complementary strand of DNA, we need to pair each nucleotide on the given strand with its complementary nucleotide. In DNA, adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G).
The nucleotide sequence CCAGAAGTG can be paired with its complementary strand by replacing each nucleotide with its complement, as follows:
CCAGAAGTG
GGTCTTCAAC
Therefore, the complementary strand of the given DNA sequence is GGTCTTCAAC.
